New TomTom GO devices

Has anyone seen the new TomTom GOs that they are getting ready to come out with. The 510 and 910 are going to be coming out in the US pretty soon, and they both have handsfree BT and are mp3 compatible. I'm excited to see what these new ones look like. Don't get me wrong, I still like the 300 and 700, but it should be interesting to check out the new ones.
