It's still available for download from M$ here:

There's just not an official page right now (and it's not been pushed out to WSUS etc. yet), but the download worked fine for me. Been running the RC2 version for a while now with no problems so I'm rolling it out to some of the PCs here at work with absolutely no problems so far.
