I don't get the "Most realistic Drums part... They look exactly like Rockband's...

What do you think?

 It has two Cymbals instead of one, and they're designed to look like cymbals as well where as in Rock Bands it looks the same as the other drums.

As for Guitar Hero IV, I dunno. I didn't like three that much, and unless the Rock Band stuff I already own will be compatible (Which i doubt it will) this would be a hard sell for me. 

video no longer available?

 Just click the link, the embedded one isn't working.

Ive been seeing this ad alot on TV here in L.A.

The user just disabled Embedding... I'll see If anyone else posted it...

Hom much you think GH4 will cost?

 The video should work now...

 It works now, I'm just a lazy clicker

OT: is this a tv ad? kinda long to be one, anyways can't wait to hear more from this game 

I don't see anything awesome here. You are asking about the ad itself right... The game may be great but the ad is the lamest commercial I've ever seen. As someone who plays guitar and has played in many real bands I want to run the people in this commercial with a Mac truck...
