In addition, Unity finally went public with their backup plan, which they posted on their blog. Basically, they put in some work on a way to write native C++ Unity scripts. As far as I know, they have no intention of finishing and shipping that solution unless it becomes necessary (i.e. Apple starts rejecting Unity apps.)

So there is a small possibility of some short-term hiccups, but in the long run Unity iPhone game development looks likely to continue. Obviously it would be better for us if Apple committed publicly to allowing Unity games, but barring that, this is about as good a position as we could hope to be in.

Any current info would be appreciated.
