"The Hangover 3" returning to Vegas?

The original "Hangover" (the only good one) was a huge hit cinematically and critically, an managed to secure as the highest grossing R-rated comedy of all time.

"“The Hangover” stars Bradley Cooper, Ed Helms and Zach Galifianakis, along with Las Vegas resident Mike Tyson, will be filming the third installment of their box-office smash series here. Just like the first film, scenes will be shot for “The Hangover, Part 3” on and off the Strip and at Caesars Palace.
 Director Todd Phillips reportedly will shoot much of the new — and final — episode in Tijuana and L.A. Vegas DeLuxe has already reported that the storyline will find the boys rescuing their troubled friend from a mental hospital."

I personally think this is a really bad idea, the second instalment in the film was so lazy it was essentially a remake of the first but in a different country. An come on the whole "mental hospital" part of the film already sounds pathetic an stupid, I for one personally will not be spending my time or money on this junk.
