Never usually any problem finding a camping space even arriving later on a Friday. However be prepared to have to walk further to find a space the later you arrive.
Queues are not too bad, usually busier on Thursday when it first opens then again first thing on the Friday but nothing that I would be concerned about. I would still advise to arrive as early as you can anyway.
I believe that the organisers have applied to be a pilot event and were still waiting on a response but that was a week ago so who knows what's happening. I understand it was a 50/50 chance of happening but I wouldn't get my hopes up 👍
