I'm quite happy with this generally. I mainly play off-TV and 3DS so it's perfect for me. However, I do have some concerns:
- Power: If it's not powerful enough to match XONE then forget it, it won't be selling. I do hope, like some others suggested, that the docking station could provide it with a power boost, and I think that's quite likely. The X1 / X2-talk makes sense in this regard as well. This should ensure, along with some more standard architecture, that third party comes along.
- Battery life: It needs to be able to hold the charge for at least 6 hours of gameplay with wi-fi on.
- Size: iPhone 6S+-size is quite fitting, I think. But how will the detachable controller alter the size? Will we be able to play it without the controller?
- Controller: We need two, one Pro-ish controller for the home screen setup, and one slimmer version suited for traveling.
