There are plenty of posts on this topic on the forums. To make the drive multi-region,someone must hack the firmware in the drive. As I understand it, this is not easy. it will also void your warranty. There is also a testing period for any new software/firmware and not many people want to be first in line to test something that could severely screw up their machine.
Perhaps when more of the new machines go past their 1 year warranty, we might see further progress.
I agree 5 changes is not enough, but there's not much we can do about it until a hack is available.
Rest assured, when one does get created, it will be all over this forum, as almost all of us want it. I don't like it but I'm content to wait.
