Well, with the idol being played, it is the perfect time for the survivor auction. The challenge will be live (not non-live like I said in mails) and it will take place at 8 EST tomorrow
You can expect to see a clue to the newly hidden immunity idol which will be hidden after the auction so looking now is pointless. If you miss check-in you may not jump in.
Immunity will not be given out in the auction because i think that Auctions that give out immunity need to burn and be buried alive and have their grave's pissed on but you may see an advantage for the immunity challenge that will take place after (it will be extremely short)
And no, this will not be riddled with insane crazy advantages, only a few.
