Well here's some good news.
One step closer.
It might just be China. I recall seeing an interview with Arne Sorenson where he indicated three approvals pending. One was Europe. I don't recall if the US had signed off at that time, so that might have been one of two. There is at least one more (maybe 2) anti-trust approval(s) still to come. Then there are a couple of exclusivity agreements in NYC that will need to be sorted out. Still several things that need to happen.
In any case, things are moving in the right direction.
