The most up-to-date buzz is that Pawan Kalyan has given a nod to act in VV Vinayak's next.  The director has described a fascinating story to Pawan, who was overwhelmed with it.  The news is scattering like a wildfire that Pawan plans to release at least three films in a year's time.  Only recently, his name did the rounds as the lead in the Telugu version of 3Idiots, though there has been no authorized confirmation from Gemini Film Circuit as yet.
 
Given that in the Hindi version, Aamir's role is not too long, it is only anticipated that Pawan will be capable to wrap it up swiftly.  Next, he might believe it fit to focus on Vinayak's film. 
 
For the moment, gossip mills are saying that Puli's release is not in the prospect.  There are signs that it will be releasing in April.  Lately, director SJ Suryah said that the film is shaping up extremely well and that he was planning to make it in Tamil too.  Though only a few songs and introductory scenes are to be filmed, the producers haven't announced the final date of the release.
