ATG in the UK is the equivalent of the Shuberts, so I highly doubt they will be selling off in a way that would mean ATG would no longer exist. That said, ATG and Sonia Friedman Productions are owned under a large venture capital group same as one of the main Broadway ad agencies. So, in theory, they could all be sold off and the general public wouldn't know because the entities would still remain in tact, but just change hands on the back end.
