We must remember that to make a phone requires more than just the processor (altho that is the most important part), there is also other thing to consider for manufacturers ie battery life, heat, UI etc. Making all thes things work together is important to make a complete and compelling product. From a business point of view, they also need to recoup what they have spent on R&D in current phones. I know that Samsung spends millions on R&D and will unlikely to have the SGS eclipsed by a better model so soon. The way I look at it the "monster" phone will be out earliest middle of 2011, most likely end of 2011.

just my 2 cents
