Well, I have some friends that have done some serious iPhone/iTouch dev - and its been a disaster. It was great at the start, but the platform is completely saturated now - and its impossible for anything other than a major IP to launch and do well.
MGS should do fine, as Apple will actually put a lot of backing into it.
