It depends on who I am making it for.
If I'm making it for Sqrl the gamer then I would drop things like BR and go with a different architecture altogether. Make the focus entirely games and gaming and make my system the most inviting I possibly can for developers.
If I'm making it for Sqrl the CEO and shareholder of Sony then I keep BR and make some modifications to the cell architecture to help lessen the learning curve for devs and probably double the memory.
