Of course price matters especially when price/performance matters. I would definitely not pay $1000 for a BD knowing how would it perform. It is no where near in the range of the LGA2011 so I would say price here definitely is an important factor no matter what you pay for. The price that I have stated there take it with a grain of salt. That is why I labeled it 'rumor' because it has OBR all over it and my assumption here is that it should price similar or more expensive than Core i7 2600K.
AMD used to charge USD$1000 for the FX-60 years ago. That is when they were highly profitable.

It will definitely perform as good or better than Intel that I can be certain of but my assumption is only limited to heavily threaded applications and not single threaded applications. AMD would have to change it sooner or later and the very old socket is becoming of a bottleneck. It is either they make a switch now or never but I do agree that it would be a waste to have such a short lifespan. As for IB, nobody is 100% sure whether the Cougar Point chipsets would limit users or LGA1155 will still be used but Panther Point is a requirement to use IB.
Based on the leaks which I would consider viable, I don't think so even in heavily threaded applications. I'll have to reserve judgement until some real benchmarks and reviews are published. Many things could have happen after that (e.g. bug fixes, clock speed fixes, etc)

The current programming model has poor multicore support and rewrite or recompile is necessary. That is why there are programming languages like OpenCL to simplify and make better use of multicore without diminishing returns.
Not true. Some compilers and programming APIs already support multi-core (including ICC). Intel is also trying to introduce MIC (Many Integrated Cores) to simplify porting of applications (easily by adding a few lines of pragmas and directives). However if you try to port applications to OpenCL or CUDA, that would require a major re-write. That is why the number of GPGPU applications for normal tasks are so few, while you will find most of them in specific HPC applications (mostly in CUDA).

It depends but more and more programs are getting on the bandwagon to utilize more cores as they possibly could despite the difficulty posed by making a program to be multithreaded. Definitely not all programs will benefit from OpenCL or could benefit from OpenCL but developers are getting there soon. OpenCL is quite a recent development and not as common as the C language but it is quite similar to C in terms of writing so I think it wouldn't be too much trouble for developers to learn it.
Being highly parallel intensive computation and multithreaded is not the same thing. Similar to "C"? Not really, more of an "API". Have you seen how the codes look like?

Llano and the whole Fusion concept will only become more popular if AMD manages to work with developers to push the development of GPU accelerated programs. They are trying and some software developers are making GPGPU accelerated software but if they fail then the Fusion platform is a flop.
As mentioned before, porting applications to GPCPU usually requires major re-writes, re-code and re-compile. That is why there is so few of them. Check
True Fusion: AMD A8-3800 APU Review. Page 20: GPGPU Applications (seems to be the only review that test the very few GPGPU applications around).

Last time GPUs are meant to push pixels but as time goes by we get GPUs that are becoming more and more multipurpose. That is what CPUs are today, they are multipurpose and no fixed function logic compared to last time and that is what makes modern CPU what it is today. We all know that AMD is pushing their GPUs to be more
compute intensive and more like a general purpose processor compared to pushing pixels, becoming much more like CUDA cores. GPUs these days are plenty powerful no thanks to console counterparts slowing down development so GPU compute is another market to tap.
Not all programs can be GPGPU accelerated, because GPGPU hardware still has many limitations since they work on fixed sets of data but not with dynamic data (those with lots of data dependency for example, such as ray-tracing which is still until today best done with CPUs).

CUDA was good but since it is proprietary to Nvidia, development is slow as with any closed source software. Make it open source like OpenCL then we can see development becomes faster. There are already AMD APP accelerated software, I forgot where is the link already but you can search through this thread, I have posted something about Cyberlink before. As with any programming language, it takes time before it becomes popular(if). We'll have to see the market's adoption rate towards GPU accelerated programs and web browser GPU acceleration is a good start.
CUDA is already highly popular in HPC, you can see that from the HPC hardware (majority HPC machines use Tesla, including the latest Cray supercomputer). Unfortunately OpenCL is still not that popular (probably due to having some platform specific APIs for different GPGPU architecture from each manufacturer, AMD have their own coding structure while NVIDIA have also their own coding when it comes to optimizing for fastest compute tasks). Then there's also DirectCompute, another recent competing API for GPGPU from Microsoft. Thus often programmers usually tend to stick to one already familiar API (such as CUDA). It also does seem NVIDIA Tesla hardware is more popular because it perform specific tasks better than AMD Stream (e.g. Folding@Home).

Follow the oBrbvsky blog test result
Performce is between i5 2500k and x6 1090t......
Abit sad on the result...

OBR the joker? IMHO take his results with lots of salt or ignore them altogether (after the stunts he pulled).
