To be fair, they have been relaying grass down..
The map will be done in layers. Restaurant names and logos will be one of the last things added.
However, to support the theory, the Burger King in that location is no longer mentioned on the Thorpe Park app, which also doesn't include I'm a Celebrity, nor Sticky Sisters (which appears to not be returning as it's been removed from their website also).
I must stress that I don't think it means anything immediate. However, one cannot deny that the removal of multiple things in one area gives some hope..
