Microsoft has been thinking about Windows 8 for a while now even through the production of Windows 7. Some information has been gathered by our friends over at Ars, and all of this said information points to possible 128-bit versions of Windows 8 and definite 128-bit versions of Windows 9. Update: Other technophiles better-versed than I in this whole 64/128-bit business pointed out that it must be for the filesystem (such as ZFS described in this article) rather than the processor and memory scheme.

Unless the processor makers get smarter about how operating systems are structured, there wouldn't be a technical benefit to going to 128-bit.
On 64-bit systems, you already pay a performance penalty for dealing with pointers that are twice as large. I know this penalty is on the order of 20% in Java, and it's probably not much better for native code.
About the only only practical uses I could see for 128-bits are for filesystems, or for ultra-high-end compute clusters that run thousands or hundreds of thousands of virtuals.
