Last I heard the target date was sometime in July; so you're looking at waiting another month or so, if not more. The Via KT266 still has some work to be done on it before it's ready to make another try in the marketplace. IMO, after all the problems the MSI K7T 266 went through and the stories that I heard of sub-standard performance and instability, I wouldn't trust a KT266 board as far as I could throw it. At least not until I see at least half a dozen positive reviews from trusted websites.
