CVG, Epic Games vice president Mark Rein has expressed his belief that graphical advancement in PC games will be partially reined in (OOF!) due to the limitations and financial viability of consoles. "Publishers are generally putting their money where the highest return is, and in the past that's been on consoles and I think that's still the case," said Rein. "So if you build the game that's a really super amazing high-end game, how do you make all the money you could make from that game, because it'll be too high end eventually to be on PS3 or Xbox 360."
As a result, Rein expects consoles to "pretty much define what the next five years of games look like on the PC" and titles pushing the DirectX 10 envelope to be in the minority. PC versions should, however, benefit from several enhancements a la Gears of War. "That's the value to me of the PC, that the source content we have is still really high resolution, much higher than we can show on a 512MB machine. You can use that content on the PC, you can express it in higher resolutions and higher frame rates and turn on more effects. I think that's what you'll see, PC games where we turn it up higher."
Though it sounds like console technology is cramping the PC's style, the Xbox 360 and PS3 (and those who develop for them) are still immersed in the design transition from single processors to parallel architectures. There's a lot more wind to be coaxed from those sails yet.
