Do you think Windows 7 will ship with the 6.1 version number? Or are they just using it now for testing? Then will Windows 8 be version 7.0?
The windows 7 developers have stated that Win7 will ship with a 6.1 kernel version, to make sure apps don't break in win7 that work on Vista. Compatability is important this time around after all the criticism (unfounded imo) that MS received about Vista. The next version may be kernel version 6.2, or 7.0, or they may skip to kernel version 8.0, it's only a number so it doesn't matter that much, if they're willing to break some badly coded apps/games.

It's also funny to me that meow has not come back to tell us what the hell a '2d graphic mark' is where XP-64 is eleventy billion times faster than Vista. *snicker* silly XP fanboys... Obviously his whole graph is a complete fabrication.
