If there is another delay, and Vista can't be delivered in May, or June, or July, I think there will probably be an RC2 and maybe even an RC3, but Beta 2 and RC1 will not be extended.
Remember Uncle Microsoft didn't give you free software, you are supposed to be testing it. They are not going to extend what will by then be superceded and outdated test software.
If you are using Beta 2 as your production operating system, and hope to be able to transition it to RC1 and then to the Release version, you are probably going to get yourself in a lot of trouble, and unless you are doing a lot of backing up, you have a very good chance of loosing your data.

If there is another delay in the final release of Vista and it goes past May 31, 2007, do you think Microsoft will issue a patch to all those who will be running either Beta 2 or RC 1 so that they will not be stuck with an OS that stops working at that time?
