In my previous post I created a Virtual Machine with new beta of BizTalk 2010, which is now released officially. There was a virtual launch today Thursday 20th of May and you can have look through here. There you are able to download the beta, but also look at presentation from Ofer Ashkenazi called What is new in BizTalk 2010 and have access to certain links.
I can tell that creating and installing BizTalk went fine without errors and issues so far.
