Todd Howard said directly back with Oblivion that the 360 is their primary development platform. Meaning, it is ported to PS3 and PC, with any necessary changes made for the platform, IE controls, and Graphics settings menu for PC. I know the point you have been making, but its wrong. Thats the point I have been making. More game data, yes, we both agree on that. Enough to merit 2 discs, give that the game will be exactly the same, content wise, not a chance.
Why would I be bothered by the PC players "enjoying an overall better game" when I myself am a strictly PC gamer? (Nintendo DS not counted) Only console Ive ever owned was a Gamecube and I only ever bought 3 games for that.
That may have been the case back in 2006, but they cannot get away with that now. PC gaming has progressed a lot, to the point where porting a game from 6-year-old hardware is very inefficient if they plan to get the most out of current technology, or even technology within the last 2 years. Oblivion =/= Skyrim. It's a whole new beast. And you have nothing to backup your argument but Oblivion interviews from 6 years ago, and game data from games running on old engine technology.
