So far no news, and I don't expect any within the first month. The same organizers had one smaller event a few weeks ago. Initially they had a lot of entries from the UK and The Netherlands, but the authorities didn't allow any foreign drivers. They had spectator areas limited to 200 spectators, outside those areas no spectators were allowed. Spectators could buy a ticket for a certain zone and only go there. Ticket sales depends on the rules that will be decided by the local authorities. Prices could be high, as there's huge demand, regardless on how many spectators will be allowed. I think we can forget about a "normal" spectator experience we were used to.
