Which brings up the question...
Will the new "Flight" even run on older OS?
W3 statistics for August, compared to January, of the OS population who visited their website:
22% Windows 7 (+11%)
11% Vista (-5%)
53% XP (-7%)
x% other
There is still a huge population running XP (I don't understand why... It's ancient!) so I would imagine there is some possibility of it running on XP, but people seriously need to consider upgrading. Support is running out. It's like running a car which will be refused any future servicing.
Microsoft want people to upgrade so a lot of incentive will be with the two Aero operating systems, but XP support will probably still exist. But in this turn of the decade the fanbase should really consider upgrading - Not just to play games, but to keep their computer secure in the first place.
