It's on cask at the brewery now. Circumstantial evidence but they usually put stuff on cask first. I'd personally be pretty pumped about a release in cans.
I know they were planning this as they were real happy with the beer itself and guayabera just hit the tasting room on cask which generally means it's close to being ready for kegging and canning. So I'd guess soon, but I haven't seen any official news.
Heard it will be a little while before they can this, but there is a new batch ready and it's on as a Crowler/growler option
