I think I saw a team member post a while ago that anyone whose order is still a long ways out, but needed it now, could call them and get their UM2 order converted into a UM1 order since those are in stock and ready to ship.
Personally I'm willing to wait however long is needed to get my UM2, although given that the timetable at the beginning of this thread is no longer being followed it would at least be nice to get an updated one based on current throughput.
