I think this release in 2009 is a bit of a rumour, a bad one really, there's no way as to that because MS is itself making the Vista SP2 and I don't see it released before February.
I'm not too excited about Windows 7 either. Its nothing but a Vista repackage. The base of the OS, the kernel and the Driver model remain the same, so its basically maybe some libraries and features in Windows 7 which can be far outclassed by third party softwares on Vista. Moreover, I can see Windows 7 being blatantly overpriced, after what they did with Vista!
Vista's a fine new OS in its own. I'm not bitching about a change to a new OS - infact I was one of the earliest people to adapt Vista, even before SP1. But that was because it was an overhaul, a complete overhaul of its 5 years old Predecessor. But repackages? No, thank you.
