Take a look at this month's Spectrum -- there's an article about the Intel i680 chip, which seems to have a flat 64-bit address space. We'll have to see how quickly this chip catches on -- it looks really hot (it benchmarks at twice the Dhrystones of the MIPS chip), but for manufacturers who don't want to double the size of their external bus it may be a bit too much.
