I do think this game looks pretty good. I think Kinnect Sports did a good job of realizing part of Wii Sports' appeal was the accesible and pleasing presentation. Sports Champions just seems to have a really bland presentation whifun facch I think will harm its fun factor.
Of the sports presented I wonder how bowling and table tennis will feel when you are not actually holding something. Otherwise the sports shown look like they will be a good fit for Kinnect.
