Bringing Doom 3 back was an interesting decision on id's part. As far as I was aware, at the time and from the little it gets mentioned now, people were always in two minds about it. Was it a game worthy of the Doom name or was it just another narrow-path Zombie shooter? Still, they've obviously done their research and decided that a return to Doom 3 could be profitable, so the best of luck to them.
Somebody, obviously excited to replay the title on their PS3, asked John Carmack via Twitter if there was any chance that BFG will take advantage of some of the graphical power inside the device. The answer was short and sweet: "Just getting Doom 3 BFG to 60fps on the PS3 is more challenging than you would think."
Sony detractors are blaming the "dated" hardware, Sony fans are blaming id's bias against the console. Isn't it funny, the controversy that a comment can make?
