It seems like every new release these days has a special collector's edition of one form or another: paperweight dragons, underpants, sex dolls, whatever. The point is, every game absolutely must have one -- regardless of whether its the biggest franchise of all time or some game you've never heard of.
At least the good folks at Grasshopper Manufacture and Warner Brothers are willing to poke fun at this trend a little bit. Lollipop Chainsaw is nothing if not over the top, so they've gone ahead and included a life-size robotic version of Juliet with every super special ultra limited collector's edition of the game. Being a Suda 51 game and all, I'm sure all three of you that actually buy it will be pleased.
