Lego Potter is a rental for sure, although I would probably go with the XBox version. Multiplatform Wii games are almost always worse than their counterparts. I do like the variety in the GH DLC, and I also like Mario Tennis being on the VC.

Not sure if Joystiq is behind due to Christmas, my Google Reader is being slow, or they're moving their new release news to Tuesdays. No retail releases this week. If anything's coming for XBLA, or if there are any demos, nothing's been announced yet.
