Who wants to casual game with an underpowered box on a giant TV screen? Goofy games are fun on a 4-7" screen because expectations are low. On my TV I expect a crazy immersive experience, not "Candy Crush".
Infinity Blade, Real Racing, etc. show you CAN get "crazy immersive experience" (or near enough thereto that 95% of users won't notice a difference) on a "phone". Given an iPad Mini (retail replacement cost $250 so you know it costs less than that to make) take away the HD+ display, touchscreen, cellular radio, battery, speakers, mic, and most of the flash storage, and you've got a sub-$99 dual-core 64-bit box that ALL your iOS games - from Candy Crush to Infinity Blade III - can run on right now ... and anything you get for that big screen can, in turn, run on your phone when Mom says you have to get in the car and you want to take the in-progress game with you.
