Shinovi Versus video looks freakishly similar to One Piece (with added cleavage)

Marvelous AQL are pretty busy right now, not only do they have the PSP mystery Sherlock Holmes game coming soon, but having been working on chick-kick game Shinovi Versus. With this new trailer, I can't help thinking how close (if with a few less enemies and rather more cleavage) it looks to the One Piece Pirate Warriors 2 trailer that also came out today.

Will there be a big boy/girl split when it comes to buying these games? Or will boobs and bums trump the popular anime? Love the little figurines in the boxset right at the end though!
