When the time comes that HTC makes the release official, you'll be able to get it from two *authorized* places; sprints download site and HTC's website. Of course, like others said, there will be other places and I'm sure many links will be posted here, including updated and tweaked versions. You won't be able to get it directly from Micro$oft though.
Until then, be patient. (I'm trying to also)
