Convention season really doesn’t start until after February, taking a 3 month break for the holidays, so you won’t see him then. Check the Convention websites see if he is GOH. He normally does DragonCon as a member rather than GOH and may do other Cons if they are going in-person, just to get back to seeing people he hasn’t seen in 2 years.
He has the lead story (and cover) in the Heroic Hearts anthology coming out on 3 May 2022, so I would expect a rash of on-line interviews or in-person events to promote this in April, with Jim kicking back and celebrating May 4th.
His son, has also sold his first novel, urban fantasy but he’s doing a bit of a Joe Hill, so he may or may not be around with him promoting that.
He may also be in protracted silence if he is negotiating on a new Dresden Files show with someone like Disney or Amazon or Netflix, and we suddenly see him everywhere promoting that. I think of the recent Amazon Jack Reacher series which popped up out of nowhere seemingly. Given the tug of war over his creative input on the Blackthorne series you have got. It’s been 15 freaking years now that this major IP has not been on screen.
