Well, if you lurk on the GameDev.net, you'll know that this news is already over 24 hours old, since one of my enterprising MVPs decided to upstage me on the forums over there

Anyway...it's here!  Cool stuff... an update to the Direct3D 10 libraries, the first actual (non-beta) release of the Cross-Platform Audio Content Tool (XACT), and another update to the MDX 2.0 beta.

Just as a quick comment..the Direct3D 10 preview _requires_ Windows Vista.  At the moment though, there is no hardware that will natively run Direct3D 10 applications, so you're stuck with a software rasterizer that renders at about one frame per 20 seconds (and please don't send me a note saying we should speed the rasterizer up -- it runs slow because it was written for accuracy, not speed).  Anyway, if you're serious about adopting and using Direct3D 10, be sure to register to get on the beta newsgroups (even if you don't already have Windows Vista).
