I actually looked it up in Amazon out of curiosity, and beyond its selling pretty well there (which we know means nothing), I did notice some interesting stuff there:
1. Very favorable player reviews so far.
2. Indeed finally has downloadbale content - so, like GH and RB, you can now (or will be able to later) expand the game with songs you want.
3. Lots of new modes
4. Last but definitely not least (this is for Leo-J) - motion detection has apparently been significantly improved. I'm saying this not based on the product blurb (which also mentions this), but based on actual reviews
(e.g. : "And now the answer to the burning question you've been waiting for: did they really fix the poor motion tracking?
The answer is, happily, yes! Even though the game still uses only one Wii remote, and still doesn't even need MotionPlus, I'm happy to say that the motion tracking picked up my motions almost perfectly. It was even accurate not just to my timing, but also my arm movements and angles. The game developers made a vast improvement over the original in this department.")
