As far as chances go it seems split 4 ways with a:
25% chance of TLD on or before SNO is reasonable
25% chance of news on or before December 31, 2021
25% chance of news in Q1 2022
and a
25% chance of news in Q2 2022 or later.
Thus we have a 75% chance of TLD no later than the end of Q1 2022 but that leaves an annoyingly large 25% chance that we get delayed past Q1 and once that happens, all bets (just as they were starting October 5, 2020) are off.
Pure guess but I will go with 10% chance by SNO 2021, 50% by year end and 99% by SNO 2022 (Ex's 50% guess) If nothing by year end (2021) then can't wait for next ASM
