This is very shocking news. Monsters, Inc. on Blu-ray, which was set to be released on May 19 of this year, has been pushed back to an unknown date. All retailers have stopped accepting payments for pre-orders, and it seems like months of promotion including inserts and promos in the new Pinocchio and Bolt Blu-rays, have gone down the tubes.
There isn't much more to say; the A Bug's Life Blu-ray release is still on schedule for release on May 19 of this year, but for some strange reason, Monsters, Inc. remains to have a release date, but there is much speculation that this release could be holding off an entire year until May 2010.
Update: Blu-ray.com is reporting that "Monster's Inc. has been delayed until November, likely to coincide with the Blu-ray release of Up."
