Looks like there is somebody in Greece wants a GP.

The circuit seems to follow the recent street circuit of being in a harbour area but also goes through a park and appears to have an underground section. If it runs clockwise passing could be difficult, with only one potential passing point if it runs anticlock.
Do they have the monet to do it? I do not recall Greece as being a place with a circuit racing history.
Bernie will probably use it as a bargaining tool to get more money from some other circuit/promoter.
