First and foremost, I think it was a silly mistake of Sony to announce so many features for the PS3 and then later on cancelled it or infact, couldn't even do it. I know it sounds really out of the ball here, but remember back in E3 2005 where Sony said games on the PS3 will all be natively rendered on 1080p? What happened to that? What we get right now is not even native 720p instead. Yes, blame that on the technical aspects of the PS3, blame it on the RSX. This is just one of those things. One of the biggest feature they have planned for the PS3 is also Home, where I see its definitely taking too long of a time. Indeed, a quality experience takes time to build but without even shedding any news on it.... I'm losing my interest already.
Nearly 2 years ago when the PS3 costs $600 USD(60GB), it was definitely not a worthwhile machine. Nearly 2 years later now, the PS3 indeed has dropped alot in price. Its still I think, pretty expensive however. Yes if its in Malaysia, we get it for a nice round of RM1300-RM1400 in most cases which puts it in nice place to fight with a modded Xbox 360 or modded Wii. We have to look at the worldwide picture here though, Sony still needs to drop the PS3's price down in order to remain competitive.
After the war of Blu-Ray vs HD-DVD, eventhough it has already subside, Blu-Ray sales aren't taking off. It definitely didn't sell PS3s as well as DVD did for the PS2. Witha new technology from Toshiba(yeap, again) coming right up where it they intend to upscale DVDs up to a native 1080p image source and new format called HD VMD, Blu-Ray isn't exactly in safe hands yet. Definitely this isn't over yet, Blu-Ray is leading in the HD format sales for now but its still a far-cry from traditional DVDs. Personally, I don't see whats so exciting about Blu-Ray movies either. They don't have enough features to warrant me to pick up a copy of a Blu-Ray movie over a DVD version. Thats the main problem for Blu-Ray here.
As for the PSP connectivity, its picking up fairly well. At the very least we have now Remote acess with the PS3 from the PSP, could still be improved more. I don't use much of the remote play connectivity, so my comment on this one is fairly limited.
I think Sony knows very well, more than anyone else in this world that third-party support is critical. It was the third-party support which helped the PS1 and PS2 to push Sony to be the king of consoles. The big problem here is that because of the complexity of developing on the PS3 as well as the low-adoption rate when compared to the 360 and also add to the fact that games development cost are now atleast 2-3 times higher than it was in the PS2 generation, its hard to make a game exclusively on the PS3 and expect lots of return from it.
Its a very simple history judgement, exclusives on the PS1 sold so well that it wasn't even funny anymore. Exclusives on the PS2 are pretty cash-cows. Thats due to the fact that the installment base of the PS1 and PS2 was undeniably huge. The PS3? Still lagging in a pretty distant 3rd place eventhough they are slowly catching up now. Like it or not, Sony needs to pay for exclusives now for the PS3(they never really needed to back on the PS2) eventhough they deny doing it. Game development cost are simply way too high now.
In the end though, the PS3 is heading in a right direction albeit a very slow one. At the very least Sony got one thing right out of them this time, and thats hardware build quality. The early years of the PS1, we were hampered by dying lens. The PS2 days, pretty much from start we were haunted by the dreaded DRE eventhough it isn't as bad as the 360's RROD yet
The PS3 now, yeap theres hardware failures but its very much low enough to have a safe peace of mind when playing. I just hope Sony gets their act together again and instead of aiming for everything, aim for what a game console does best.... and thats, playing games(yea Kaz Hirai just said it recently, but whatever). Strike some deals with developers for more exclusives, decrease the price of the PS3 a little bit more, and finally stop giving empty promises. Thats the only thing which can really save the PS3 right now.
