Triple B Games have announced a demo of their distinctly Scottish take on football, Fitba "Nae arms, nae legs, nae problem". It looks great but in all their nifty marketing, I notice they don't mention the XBLA version of Sensible Soccer...
Also on their site is a version of the Blender FBX exporter script that has been tweaked for compatibility with XNA. They don't say what the changes are and I'm not familiar with the script but I know that some people have been having trouble with Blender animations.
