It is pretty clear that overstatement and hype has become the only (or the best) way for him to get low cost attention.
Market forces for his brand, leads to more of the same hype/let-down cycle.
so I agree its a valid marketing strat and so far it worked out for him, more or less.
I think people are so passionate in this thread because we want him to be better, to actually be the godsent genius that will make the ultimate game.
I gotta say no game designer made me dream like Molyneux and just for that I love him, even if not all of his dreams became reality.
But he has the vision and power to inspire, and that is rare as well.
