I had been told that a CLRified version of “WPF/E” would be shipping in the 1.0 release but I think the plan for the team is to make a lot of small updates in quick succession so that they can grow the product as customer needs expand. It’s a good strategy, but even “less than a year” is a long time to wait for managed code.
It's kind of amazing that Microsoft's UI team for their future UI isn't eating their own dogfood. There may even be good reasons for it - believe me, I know a fair amount about the difficulties of working with disparate teams who have independent development histories - Cincom's other products pre-date the entry of Smalltalk to Cincom, for instance. For Microsoft, however? These guys are all supposedly on the same team.
