[UPDATE: The deal is now live on PSN, enjoy!]

PSN games have always delivered a great value for a meager price.  Now, it looks like the deal is about to get even sweeter.  Advertisements on several gaming sites have been spotted, indicating that Sony may be giving Rag Doll Kung Fu away free for a limited time.  The ads say "Rag Doll Kung Fu: Download on the PlayStation Store on the PS3.  Hurry, offer ends May 21st.  Free game courtesy of Sprint".  When you click the ad, it relocates you to the PlayStation Blog's Rag Doll Kung Fu page, though nothing is mentioned about the deal, and the game is still regularly priced on the PSN store.

The offer may not go live until after the store updates later today, or it may just be a misprint.  We've contacted Sony in the mean time for an official confirmation.   Check below for pictures of the ads.
