I, too, have massive doubts about Fable IV at the moment, since we've not been getting any news for a while now. But then, they've just launched The Journey and they want you to buy that game now, instead of telling you they have a better game coming out soon. Also, the guy who leaks EVERYTHING about Lionhead's games, Peter Molyneux, left. I'm sure that if they're working on anything right now, they'd want to make full use of Molyneux's absence and keep it a surprise so that the next game doesn't seem as overhyped.
