The "High School Musical" kids were expecting big things for the just-premiered "High School Musical 2." But they weren't taking the big ratings for granted, either. Now, the accompanying soundtrack looks likely to debut tomorrow (Aug. 22) at No. 1 on The Billboard 200.

"I think we definitely knew it was going to do well, just because the first one did so well and there were so many fans," Corbin Bleu, who plays amiable jock Chad Danforth, tells Billboard.com. "We knew all the people that enjoyed the first movie were gonna want to see the second movie. We didn't know it was gonna become as much of a phenomenon, but we definitely knew the first night was gonna do well."

The movie's Disney Channel premiere drew 17.2 million viewers, setting a record for the most-watched basic cable program ever. The first "High School Musical" drew 7.7 million viewers in 2006 and spawned a soundtrack that was the year's best-selling album.

Bleu is confident "HSM2" will compare well to its predecessor. "We didn't want to recreate 'High School Musical' or copy it," he says. "I think we went in just to create a separate, really good movie."

Bleu says that he and the other "HSM" stars are "in negotiations right now" for a third movie, which Disney would like to shoot later this year. There's no word yet on whether "HSM2" will spawn another cast concert tour, but Bleu -- who's on the road with Aly & Aj to promote his debut album, "Another Side" -- is certain that none of the cast are interested in learning how to skate for the upcoming ice show production.

"It was very funny; we all heard they were gonna be doing an ice tour, and we're like, 'What?!'" he says. "Then we heard our choreographer (Charles Klapow) was working on it, and we've heard nothing but great things. He's amazing."

"I think it's a whole separate thing to what we do," he continues. "There's a point it can get to overkill, but I don't think they're pushing it too far. If I was doing the ice show and the touring show and then the concert on top of that, that would be one thing. But they're all kind of their own things."
