Pure speculation of course. I don't know or have any idea, because it shouldn't be a simple solution, at least not with the way stuff works now or is designed.
Thing is though, I think this is designed to be an mcm, not just two gpus on a single board, I don't think there will need to be an external bridge chip. Think about it, if they have a shared ringbus, then that means this is more than just two rv770s in a dual die mcm, there has to be some modifications to basically meld the chips to be detected as one thus eliminating the need for a bridge chip. That's probably the whole point of doing this rather than the 3870x2 design.

Man I just wish we'd finally get some legit info already, or if we have, that ati would confirm it
