Looking at the screenshots,the game looks absolutely amazing.The 3D engine allows them to present each character's personality in a more natural and effective way.I like what I'm seeing.

New character sneak peek.
Book.
Edit:There's also a French Bread stream(http://www.ustream.tv/channel/%E3%83%91%E3%83%B3%E5%B7%A5%E5%A0%B4%E8%A3%8Ftv) at 23:00 Japan time today,which should reveal the character in more detail.
FYI from the limited amount of footage(which is like the announcement trailer)it looks like it plays quite differently than MB or games like AH3/BB/GG,though it does borrow at least one mechanic(in this case Reverse Beat)from Melty.
So I don't know how much that will help you...
