I don't think it will be comming with the update, I'd like to think that T10 would have announced it with pomp and celebration "Teh demo has landed!!!11" they would announce and we would cheer and celebrate and say we were wrong to get so upset at them.
Although....
Perhaps it was a ploy? What if MS just held it back to have a real headline for the update? Ahh, that would explain both why it's been so long even though the real game got certified, certainly the demo would have. It would also explain Microsoft's opinion on cruelty to humans, I guess we won't see any big cheques from the going to Darfur any time soon....
Well, whether we like it or not, we'll just have to wait and see.
