Metal Gear Solid 4 re-designed for an arcade machine. You'll play a 16-player match with (mostly) CPU-controlled characters, although there is an option for mulitplayer with real people. Oh, and it has some 3D effects.
It's like the F-Zero AX of 2009. I guarantee that if this ever leaves Japan, it will be so expensive that places here that manage to get one will only have one.
