Intel's next GPU to be Pentium MMX-based?

Last night, I was sitting around thinking about Intel's forthcoming discrete GPU, codenamed ''Larrabee''. Specifically, I was thinking about how Larrabee will have lots of simple, in-order cores with a short pipeline, and it occurred to me that they might look something like Pentium cores. And lo and behold, I awakened this morning to a rumor that Intel is reviving the Pentium MMX microarchitecture for Larrabee.
