Windows 7 Beta / RC / Final Version

[victord66]

I have the beta build and like it very much. It runs quite well on my pc. It's installed on a separate partition. I understand that when the RC is out, I should wipe the Win7 partition and install the RC fresh. My question is, when the final version is out, will I need to go through this fresh install once again, or will I be able to just upgrade the RC to final? For me, there's a lot of work to do a fresh install and if I need to do it twice more, I'd just prefer to skip the RC and wait for the final. Any thoughts? Thanks.
