Lichtkreis, yeah. The hell?
Also isn't it hard to fight with pumps?
On another note, if they are going for a new soundtrack, they better make some catchy tunes, and rock. The last thing I wanna hear is some hip hop in this game. But guessing from the first teaser the music is going to be good. They might even have some things up their sleeve since they don't have to rearrange old tunes for Melty
Also I expect animations to be awesome.
