No, that's exactly what the terms are saying you _can't_ do. If you used something like GOAL, you wouldn't be starting out in Objective C, and thus you'd be in violation of the new terms.
Thanks. Sorry, I misread. And that's an interesting point too, because until now, an argument I commonly heard in support of Apple was, "At least the App Store is better than the console game environment."
Right, none of them have the complete monopoly to insist on exclusive titles. Notice how big a deal they make it when they do get a studio to do an exclusive.
Apple can get away with this for now, then when WinPhone7 comes out (or somehow they get some real competition), start backing off if they need to. In the meantime, they'll build up more developers that have developed skills in iPhone only tools.
