How different is Lumines on PS2?!

I love Lumines on my PSP and between all Lumines 1 & 2 had to offer, I didn't think the PS2 version of Lumines could get me to buy it. That is until I got an e-mail from Sony's Playstation Underground describing what Lumines Plus was like. The description says "Based on the film, a trio of unique characters use their skills to solve puzzles & succeed in combat." What a departure! Not only that, but this means there's a Lumines film in the works. Strange that the game is being released before the movie. I can only hope a combat laden version of Lumines hits PSP someday!
