I have mixed feelings about this at the moment.
There's 3 gameplay vids but they seem a litle dull.

If it's coming out in the west then I'm grabbing it. Never had a chance to play the PS2 version.
I only played #1 on the PS2, but I absolutely loved it. I was planning on getting 2, but when I heard about this I decided I'd just wait for this. Depending on when/if a NA release is announced, I might still get 2 for the PS2, because the frist was just so good.
