If this is what AAA traditional gaming studios are going to do with iOS and their properties, I'm fucking in.gif. This is a great idea, and any dissent in this thread is misplaced. XCOM has proven the validity of iOS as a platform for turn-based strategy games (and likely RTS, as well, given some of the novel attempts). The touch interface is perfect for these kinds of games, and the turn-based format was born for mobile. I'll take this kind of thing over Deus Ex: The Fall any day.
If only it was portrait mode, it'd be (theoretical) perfection.
