luckily i think that john carmack is so filthy rich and such a perfectionist that he will simply build the best engine he can - and then tailor it for rubbishrubbishrubbishrubbishbox. So us pc gamers will still get the treat we've been waiting for.....if only it were so with other companies (ie ion storm). The problem is.....and as was stated by directhex - the companies that liscence the engine will not be in this position and so will simply use the engine in 'Xbox mode' - and then release this with mouselook on the pc........so a frustrating future of disapointing amazing games lays ahead in my view.
On a different note - my mate has an xbox - and gets the official mag. I don't know but, seeing a review of deus ex 2 with a huge sticker " only on the Xbox" really winds the f*ck out of me.... i mean helloo ..... microsoft pretending the pc doesnt exist is just a little $60 billion too far....
