It will not be possible to change the version when upgrading, upgrade from 32-bit to 64-bit, or upgrade from Windows XP to Windows 7.

The published dates seem to confirm the hypothesis that they want Windows 7 on the market for the end of this year, or at the latest for the beginning of the next. Recall that, in any case, Microsoft has not yet talked about official dates for the distribution of the final version of the new operating system.
