Parallels RC2 over 2GB on MacPro

It looks like the problems met by MacPro users with Parallels Desktop are eventually reaching an end with the coming out of parallels RC2. The long expected bright new feature is full RAM support for MacPro and iMac Core 2 Duo, which means you don't need anymore to artificially limit your memory bank to 2GB.
Less expected but potentially interesting for developpers is support for Leopard and support attempt for Vista.
