This news has gone rather unnoticed, but it looks like Pixar's 2001 hit Monsters, Inc. will be arriving in the Blu-ray 3D format sometime soon, although we have no idea when exactly this will be.
Amazon has a 5-disc Ultimate Collector's Edition listed for pre-order, and Disney Movie Shop has also put up an offer which will save you $8 on your purchase of this Blu-ray combo pack. However, both sites claim that this release is "coming soon", but neither one states a fixed release date. I guess we can expect this to be out sometime after Monsters, Inc. 3D has hit theaters, likely around January. One thing's for certain though, the Blu-ray 3D of the film will be out by February 18, 2013, which is the date that Disney Movie Shop's offer expires.
No word on whether or not this pack will come with new bonus features or not, but chances are that it won't, but Pixar could always pleasantly surprise us.
I do not yet own Monsters, Inc. on Blu-ray, so I'll hopefully be able to pick up this release. Be sure to also check out A113Animation's review of Monsters, Inc. in 3D, it'll give you an idea of what to look forward to in the classic comedy's re-release.
