You can install the Windows 7 Beta, then install the RTM version when released, but AFAIK MS hasn't officially stated they will support this, yet. I can't say I recommend doing this, but 7 beta does seem very stable. I know many people who have already made the switch.

The official stance of MS has always been that they do not support upgrading from a beta version to the RTM release, or even from one beta to the next. Basically, they are concerned with fragments of previous versions being left behind that cause problems with the overall performance of the system. However, I was able to find
this link that describes a workaround to get the Win7 installer to allow a beta to RC or RTM upgrade to take place.
