I guess that depends on your definition of a "release date."
To me, Q4 (A Christmas Carol) is a release date, as is June 2010 (Cloudy with a Chance of Meatballs). In a way, even knowing Avatar 3D won't happen in 2010 is sort of a "release date."
At the very least, it's "release information."
Anyway, I did start a thread that has the information Lee has provided. It's titled "3D Bluray Release Information." I guess we'll see whether or not that proves to be useful - but it's there.
