Just want to add - many people are taking his comments as referring to the potential 'end state' of the engine/game.
Bear in mind the context of his comments are more of a 'status of development so far'.
When he mentions the challenges of handling split memory he's not talking about a situation where they're finished and have done the best they can - he's talking about an ongoing development effort, for example.
From his full comments the clear indication is that currently the status of development is as follows:
1) PC - most stable and furthest along
2) 360 - next most stable position
3) Ps3 - next most stable position
Now, we're talking about arguably the foremost developer of gaming engines in PC history, so the above is not a surprise.
However, given id's track record of well optimized code and dedication to getting the code right vs good enough, I have no doubt that the 360 and the PS3 will in their turn end up in a position alongside the PC for this engine in terms of target metrics (e.g. 60fps, etc).
And for those who might be worried by the performance of Enemy Territory (which wasn't great on HD consoles) - remember id made it clear that was a PC only engine that was ported to 360 and PS3 with minimal optimization and variable results.
id Tech 5 is their first engine developed from the ground up to support HD consoles - so why don't we give them time to finish it and review the results before we judge how well a job they did?
Try to be reasonable... its easier than you think...
