Actually, I don't think you should take away the DNR at all. I'm pretty sure they DNRed it specifically because of the 3D release and the 2D will most likely be just a 2D version of the 3D master.
Also, given LFL's history, it's quite possible that the new TPM master is 1080p only (not necessarily the scan but the master) so there's no guarantee that the resolution would be higher either.
