Happens all the time to exclusives on both HD consoles.
It should be ignored and the OP is rather silly to imply it means people are 'running scared' as that just whips up more arguing. Were 360 fans running scared when voting down Uncharted 2 for example? I know Selnor is oddly determined to have the 'best graphics' on 360 but that's almost impossible to agree anyway and I wish he'd give it a rest personally with this crusade. At different times each console is going to be home to some nominal 'graphics king' and it's just a waste of time really.
As for the posters on Metacritic... it's just idiots being idiots - although sites like Metacritic could make like a lot easier by at least not activating user reviews until a game actually releases.
Try to be reasonable... its easier than you think...
