I’ll let you read more details on ScottGu’s blog, but here’s the gist: We’ve had tons and tons of terrific feedback about the current Beta 2. Based on all that feedback, in order to make the RTM of this version of Visual Studio as stellar as it can be, the official release of VS 2010 and .NET 4 will be pushed back a few weeks.
A Release Candidate (RC) is planned to be made available in February, which will give us all the opportunity to take one more test drive before RTM.
So while it’s a slight bummer that VS 2010 is getting pushed back a little bit, I think it’s a good thing overall. Personally, I’d rather get the product right, rather than “right now”.
