According to an interview with Epic Games' senior producer Rod Fergusson, developers for the Xbox 360 may be reaching the outer edges of what is graphically possible with the console. In an interview with Gamasutra, the Gears of War / Gears of War 2
head says that recent advances and refinements are pushing the system further than expected, though he still believes there's some room to grow. In Fergusson's words: "I think we're certainly approaching the upper end of it, as far as what developers are able to do with it, but just looking at all the demos we saw today -- ours and others -- it's clear that all the games just keep improving, and keep pushing that bar." Of course, there's a long gap between pushing a system to its limits and starting to look around for its replacement, though since we all know another iteration of the Xbox is inevitable, none of this news should come as any surprise. They have a name for things like this... progress.
