An interesting read. Intel is saying that there is no need for a 64-bit desktop chip until perhaps the end of the decade. They're probably right as well, what besides large servers and workstations use more than 4GB of RAM?

Another technique for expanding the memory capacity of current 32-bit chips is through physical memory addressing, said Dean McCarron, principal analyst of Mercury Research. This involves altering the chipset so that 32-bit chips could handle longer memory addresses. Intel has in fact already done preliminary work that would let its PC chips handle 40-bit addressing, which would let PCs hold more than 512GB of memory, according to papers published by the company.
