Ars Technica has a fine post about it : http://arstechnica.com/microsoft/news/2009...8-windows-9.ars
Whoa. That's ridiculous. From Wikipedia:
128-bit processors could become prevalent when 16 exbibytes of addressable memory is no longer enough (128-bit processors would allow memory addressing for 340,282,366,920,938,463,463,374,607,431,768,211,456 bytes (~340.3 undecillion bytes or 281,474,976,710,656 yobibytes ). However, physical limits make such large amounts of memory currently impossible, given that amount greatly exceeds the total data stored on Earth.
I think maybe Windows 8 should be 64 bit only, and then maybe do Windows 9 at 128 bit. For the time being though, lets get 7 here and running.

Microsoft will have to do a lot of planning if they go ahead with 128-bit. The Vista example is scary. We all remember how the poor souls on Vista 64-bit were hauling and screaming for software but nothing was compatible i the beginning. And stupid Flash still don't have a version for 64-bit.
thats good news.
more bit means more precise math. which in turn contributes especially to increase performance in graphics.
