Nope. Nobody knows anything yet. Don't worry, as soon as we have the slightest inkling of when it will re-open, there will be at least 5 threads about it.
Oh gosh, we haven't even gotten SSE back up yet LOL.
However, I think it's far more likely to see some sort of soft opening for TSM than we would for SSE. Disney doesn't do soft opens for craps and smiles, they do it when it serves their testing purposes. Something like SSE (much like HM, IASW, PotC's rehabs) where they are re-doing an existing attraction see far less "soft openings" than new attractions (like Laugh Floor, for instance) which are new experiences and may see sporadic openings up to a couple of months beforehand.
This whole refurb has been INSANELY hush-hush. Feels like it'd be easier to find out if there was really a second shooter on the grassy knoll. :brick::lol:
