With the Wii and rail-shooters going together like peanut butter and whatever goes good with that it's only a matter of time until companies get around to porting more of their stuff to the console.
I played Gunblade NY a long time ago and the only thing I remember about it is that the massive gun it used made my arms numb after awhile. For some reason I can't imagine the Wii remote having quite the same effect. Still it's always nice to have ports especially when it comes to games I honestly never expected to see again.
Still wish I could get one of those actual guns from the game though. It's bad enough I couldn't get my very own special ops gun for the Ghost Squad home port, that thing was amazing in the arcades.
