@BamaInArk-
Basically, you'll get it when you get it.
Roku rolls out its updates individual Roku installation by individual Roku installation, with an update schedule known only to Roku. If you have multiple Rokus, they may not become eligible for the update at the same time, even if they are the same Roku model.
I haven't been on my TVs yet today, but as of last night all of my three Roku installations were still on version 11.5.
