No mystery about what is going to happen here. He is going to stall for as long as possible while hiding his assets,and then take a plea bargain at the last minute and be pardoned by Biden.
I suspect the only reason he hasn't done this already is he is waiting for the mid-term elections to be over so no Dims running for office are hurt.
The plea bargain will probably come right after that so there is time for Biden to pardon him and the voters to forget before the next elections.
