I hope I'm wrong but this has all the hallmarks of not happening. At all.
If the people that are behind it think that a total news and marketing blackout is a good decision then they're wrong and they're clearly not business people.
Track prep, starting gate, track lights (ie green and red lights for racing) airfence (and on and on) all need sorting. And that's before you assemble a team. If someone was to confirm who's promoting the venue and where they're at with the above (and more) then maybe fans would feel excited or at least confident about the future.
Silence does you no favours and no news is always worse than bad news.
