Also, my daughter is very upset that it is not coming out in 3D on Blu-ray.
I'd HEARD one poster say he'd heard from a Disney Club representative that they'd been told there were disk pressing/mastering problems on the hard disk, and that was what caused the delay. (And was immediately shouted down, discredited, blacklisted, and had all his personal faults exposed to the world for suggesting that Disney wasn't doing it because they were conniving and greedy just like they were on the Oz disk, and were trying to (pick one) A) admit that 3D was "dead", B) move to digital downloads, or C) figure out how many times they could make us buy 3-disk editions. )
It's hearsay, but when it's hearsay from a retail outlet, where they would be the first to get the news from HQ about why their big shipment isn't coming and shouldn't sue, it's out of the realm of impossibility....It might also explain why the new Tinkerbell movie is "mysteriously" not coming out on 3D as planned for March as well.
Still, if even a two-week delay pushed the 3D off of its big day-date debut, it's started to bring up theories whether Disney might want it to reappear in fall, with better-organized hype and possibly with two or three other cross-marketed 3D titles.
The lack of a Pixar this year has had fans wondering whether we'll see one more re-rendering, and there's been rumors floating around about what might be "in the works". Let's just say IF Pixar announced an Incredibles 3D for later this year, I would very strongly suspect Frozen for the holidays.
