" On a more positive note, Banana Blitz is easily the best-looking Monkey Ball game ever, with huge levels that are now more like small worlds than bare-bones platforms."
I'd say that's a step in the wrong direction. The Wii has nothing to do with good graphics really - but more to the point, Monkey Ball was never about the visuals. Easily the best games of this gen, clearly that's not the case with the next gen. They really should have done Monkey Ball 3 on the GC.
