His biggest pet peeve with the console market is how closed off it is: you have to apply to be a developer and get a special development kit and get product approval from the hardware manufacturer, etc. (As opposed to the PC market, where anyone can develop and game creators can release content updates, point releases, and so on.) That's just the nature of the market. If the PS3 opens up, it'll be more like the old Commodore Amiga, a platform anyone can use for a variety of applications. Certainly Microsoft will never do this with the Xbox product line, but Carmack is holding out hope that Sony could experiment.
