From an article by Michel Roth at ThinComputing.net, it looks like the XenDesktop Tech Preview that was slated to be released on 29 October has now been postponed. According to a post in the Citrix forums, "The Tech Preview Kit will be available in early November."
That's not terribly surprising, as there hasn't been a whole lot of time since the completion of "The Acquisition," but it is a little bit of a bummer. After so much hype at iForum, lots of people (myself included) were very excited to get their hands on it, as much for XenSource as for Ardence Desktop.
Keep your eyes here and on Citrix's XenDesktop page, and we'll cross our fingers that Citrix can put out a good product sometime in the next few weeks. Personally, I'd rather see a good release than something shoehorned into an unrealistic timeframe, so I'm glad their taking the time that they need. So long as it's not too long.
