pregunta de bailar

Hey, this is directed to anyone who can help me out w/ something. Apparently there is a new dancing game called IN The Groove slated for PS2 release in like the next week or two. My question is DOES ANYONE KNOW ANYTHING ABOUT THIS GAME???!!! It says that they have a machine at Golf N' Stuff, but I wouldn't know since I don't get out much. So my 1 major question is:

Is this worth the 40 bucks that it's been MSRP'ed, or is this just a rip off of DDR? Or is it an improvement? I heard a sample of the music on the official website, but it seems more than just a little canned for my taste. Am I just misinformed and this is the next best thing since sliced bread or is this a total waste of time?

I heard that it has these weird shit things you can do like make the arrows rotate or spin around or (can you believe it?) make the player hit 3 or all 4 steps at once. Would those really make a difference, or are they just cheap bonuses?

If you know, I'd like to know.
