Windows Vista to Windows 7: What will be the Upgrade Cost?

Ok, so Windows 7 is on the horizon, and going by the previews, its definitely going to be much better than Windows Vista. I have read a couple of articles on the net discussing how much Microsoft should charge for the upgrade from Windows Vista to 7. From those who are hoping for a free upgrade, to those who say its not gonna happen, theres even a leaked best buy memo supposedly detailing upgrade costs for the same. I am NOT referring to the official upgrade program which says that anyone who buys a system/copy of Vista like 6 months before the launch gets a free upgrade. I am referring to older users of Vista (like me, for example :P) who are looking to move to Windows 7. If the memos to be believed, the average cost from an upgrade should be half of what Microsoft charged for users moving from Xp to Vista. While a free upgrade for users of the obscenely priced Windows Ultimate sounds really good (disclaimer at the bottom ;)), its probably just a pipe dream.
I am still hoping for some gesture from Microsoft towards Vista users though. Thats one thing that would really make 7 worth getting. Of course, the very fact that it would hit their revenue/profit estimates takes it to the ‘Dream On’ category. 🙂

1. I own a copy of Vista Ultimate and need that cheap upgrade option. 😛
2. Need to try out the 7 RC too. Downloaded it long back. Just havent got the time to play with it, yet….
