Guys, we're talking about the master of misdirection here, remember? How many times did he lie and say he was done modifying the films? How many times did he say the OT would never be released on DVD in any form? How many times has he retconned his own personal history of the making of the films?

To that end, how do we know he hasn't already had better scans done of everything we want and is holding out for future releases? He's sticking with his "2K scan" story for now because that's the limit of what current home technology can deliver. If he released better versions now, he wouldn't be able to infinity-dip later on by selling it to us again as yet another "improved" version.
