I don't even have anything to say about this... I just love Ghostbusters and if this game ever comes out it'll be sweet.  I'll buy a Wii just to be a dork and have this thing.  Apparently these are just concept images and no one knows how it's going to work.  Here's a link to IGN's coverage of the game.  Apparently it's supposed to come out on June 16th, a little over two weeks from now.  I have to say I hope the game doesn't suck because having a sweet proton pack is my dream.  Who doesn't want to shoot ghosts with a twisty beam?  Whatever you do, don't cross the streams...
