I think Lei Fang style was made in order to not cover so much range, but with plays as closet instead, that may be why she don't have 6H+KP/8KKP from DOA4 any longer. Anyway, you know a character can't be good in all the ways.
Lisa with amnesia actually sounds so interesting, but I don't know if that would work for her character.
The stage isn't that bad, it have obstacles, jumpable objects, water, and a dinosaur who attack you randomly. The only thing to claim about this stage is to have a better design. But this...
I agree with Rawbie, the poster and the Momiji pose doesn't mean anything, but the tag animation with Leon and Zack in the beach is really really interesting. But I'm not going to have high hopes just in case xD
They better take their time until the release of DOA6, I don't want to first buy the game and then a year later need to buy DOA6U because the original was lacking of content that should have been there in the first place. So plese, make things right TN, you now have the money to do.
