I have recieved a response from a representative from Warner Brothers India.

Currently it is not certain when TENET will be re-released as there are new movies such as Argylle coming out this month that will be occupying IMAX theatres.

However, I have also been told that Villeneuve's DUNE will be getting a re-issue next week which is something to look forward to.

Keep sharing the petition so that the demand for this re-issue is loud and clear!

Attached below is a screenshot of the E-mail response I recieved.
