Far be it from me to interrupt someone's self-delusional 'only I have vision' rant, but battery technology is nowhere near able to support casual gaming much less what regularly runs on current generation consoles and PCs. And pretty much, no one is going to want to tone down their "WOW" factor. I'm not even going to ponder the time and costs it would take to further miniaturize processor fabrication to come close to the amount of horsepower needed to run the most popular games.
Even with the possibility of the nascent low-latency bluetooth compression routines, there will still be way too much lag time streaming video and sound to external devices. It simply is not conducive to multiplayer gaming and there is only the faintest hint of a promise of seeing something within the next two decades.
I'm not knocking people that like "Angry Birds", but that's not exactly what most gamers hold as the standard of gaming, but it is close to the pinnacle of what is achievable today and the foreseeable future.
