Hearing through the unreliable grapevine (distributor-to-store-to me triple hearsay, internet crap chatter, etc.) that it's going to be a much smaller release than last year. One reason I saw floated (no evidence to back it up, but at least plausible) was needing to source all-new barrels post infection issues or something along those lines.
I do know that, at least on the initial run, my local store said they are getting a lot less than last year. But it's also possible ABInBev is making reductions asymmetrically, market-wise.
