GA-P35-DS3P rev. 1.0 versus 1.x

I just purchased a GA-P35-DS3P. I received rev. 1.0 instead of 1.x.

Does anyone know what the differences are between these two versions other than the change in the heatsinks?

My understanding is that rev. 1.x has been available for a couple of months, so I was a bit surprised to get a 1.0 version. For anyone who recently purchased this board, what version did you get?

Same version here 1.0. 2 weeks old.

There is now rev. 2.0. What is this about? There is no info (about the differences or the revisions) on their own website.
