I really doubt they would do something as stupid as that. Releasing it on DTH will just kill the film's chances at the multiplexes, more so considering this is the holiday season and people would like to spend more time at home.

Also, this film, like most of Aamir's films, has very little chances outside multiplexes in the metros and Tier I cities, and hence a good run at these screens is a must for them to recover whatever the distributors have bought it for.
