I think there's something here you're missing:

What if it does get approved, but only by some countries? So, for instance, suppose the US approves it, but China and the EU don't? Then, it probably won't stay grounded, because this plane is usually used for shorter-distance travel. Southwest Airlines, for instance, exclusively uses 737-type aircraft, and all their travel is domestic US, so an EU ban wouldn't affect them at all.

I for one wouldn't feel too confidant about the FAA approving this plane with the EU regulators refusing to, considering what a criminally-negligent job the FAA did in approving it in the first place.
