[citation][nom]hannibal[/nom]Not likely. The win 7 support will be security upgrades only when win 8 comes out. Maybe some small tinkering, but win 8 is so much more important to MS at this moment. It will allow commong core, common UI and common aplications in all possible platforms! It can be huge money mill to MS if and when win 8 brokes trough. Does it hapen with win 8, or a little face lift version of it as a win 9, does not matter to MS. If they make win 7 too good, it will slow down the movement to win 8 and eventually to win 9, so there is very little reason for MS (economically) to make win 7 much better.It is bad to us, but when you think how all the previous windows versions have developed after the new one did come to market, we can see that the old OS sees very little love by upgrades (the security upgrades are/have been quaranteed though).The win 8 includes some good upgrades over win 7, and win 9 will include more of them, so eventually we will move to new "tile age" if we want it or not...[/citation]
While I agree it's in their best interests to do as they always have, the release of the new OS is not an immediate condemning of the previous version, as is the case with Apple. Microsoft is very clear on their product support cycles, having published them long ago:

If you go based on this, those with Windows 7 should expect continued support and regular upgrades until 2015, with security updates until 2020. Considering the fact that Windows 7 came out in 2009, a 5-6 year mainstream support cycle with a 10 year security release schedule is actually quite generous. Remember that Windows XP received SP3 in 2008, a year after Vista was released. Additionally, Vista (Whose mainstream support ended only this year, not when 7 was released in 2009) got SP2 in April '09 and a platform update in October '09, and in the middle of those releases was the release of Windows 7. Based on previous history, you can expect at least another Service Pack in the future for Windows 7, possibly in conjunction with the release of Windows 8.
