Already done (Score 2, Insightful)

It's already on the market, and most game producers are already developing on that platform. They're called PCs. PCs are cheap, and are -everywhere-. There are more PCs that are 2-years old or younger than all of the game systems that have ever been produced combined. The 'standard' PC architecture is constantly climbing in its capabilities, so any PC game produced today, even if it requires 'top-of-the-line' hardware will be usable by most PC owners within a year or maybe two, and again, we're talking about many, many times more prospective costomers than owners of games consoles. Oh yeah, and games produced for the PC today will work on most PCs that are produced two years from now. You can't say that about game consoles. All they have to do is produce GOOD products, and people buy them. (Blizzard is grossing over $1Billion/year right now. Yes, that's Billion, and that's only for WoW.)
