Sata ? in Macbook

I have to computers. A 2009 Core duo macbook unibody and a 13" macbook pro 2010 core duo.
I am wanting to swap out the drives in the Hard drive bay but was wondering about the SATA connectivity of both.
Is there Sata 3 (6g) connectivity in any macbook yet?

I don't think for the Macbook there is (which is currently discontinued except being offered for educational institutions). The new 2011 Macbook Pros have Sata III, but yours both have SATA II.
