Would be a way for Lucasfilm to make the 3D conversions finally pay off.
Were all six shown in 3D at Celebration this year?
No, just the PT.
It was the first time RotS was shown in 3D if I'm not mistaken. I wasn't there, not even on the same coast, but I've shared my thoughts in the past about how three-dimensional RotS already looks in regular 2D projected on blu-ray. Assuming they didn't drop the ball on the conversion, it must look amazing.
Meanwhile, several signs point to this new 4k remaster of the OT having been done years ago, maybe even as early as 2008-2010. It takes a year to really do a thorough conversion of a two-hour movie into 3D. Titanic, a 3-hour movie, took more than a year. If the new 4k scan/remaster was ready before Disney even bought Lucasfilm, then they've had three years to convert the three movies.
On the other hand, I feel like we would've actually heard something about it by now.
