FFC's do not have the "infrastructure" or market presence needed to be a deal breaker for me. Most of my friends have an iPhone, and never once have I seen one use video chat, because it's far easier to text, or dial a number and get off the phone quick. Give it another year or so, and FFC might become a valuable must have feature
As for GPU...this is silliest thing to be concerned about. Why do you need a super duper GPU? To run angry birds? The app selection on Android is so awful.
I can see mandating a fast GPU on iOS, because they actually have a serious catalog of games that would benefit from the horsepower.
Maybe things will change, but I doubt it. Guess we will see at E3, but until Android sells less junk phones, and gets more consistent in terms of QC and baseline specs, I don't expect developers to waste their time.
Nvidia could help progress things by becoming the certification standard baseline for game makers.
