Japan is apparently getting a House of the Dead 4 cabinet with screens in front [b]and[/b] behind the players and a rotating set of seats. It will also apparently blast you with air whenever you get hit.
Honestly I like HotD 4 just fine the way it is, and I worry this version will be more than a dollar a play, but people seem very excited about the possibility of getting this in the US.
