Formerly known as Stealth Bastard
Stealth Inc (formerly known as Stealth Bastard) is coming to iOS according to one of its developers, Jonathan Biddle. Biddle is not giving a specific timeline, only noting that negotiating the different screen real estate between the Vita and iOS devices is a bit tricky at the moment -- as in, he has to replay the entire game three times every time there's a change.
If you're interested in Stealth Inc now, you can find it on the PC, PS3, Vita, and Android platforms. I haven't had a chance to play it yet, but the namedropping of Super Meat Boy and Metal Gear has me interested.
