I haven't tried it myself yet, I will once I get the download from MSDN today, so I can't say for certain, but I am taking Scott at his word.

Maybe not, but you may be misinterpreting. The same was true when upgrading a 2005 project to 2008: you then couldn't open it in 2005... unless you manually edited the SLN and VBPROJ files. My guess is that it's the same from 2008 to 2010, but it is just an assumption. I guess we can find out for sure soon enough. Woohoo!
