We're currently in the Closed Playtest Era™, but the roadmap for this year is already cooking in the oven.
There won't be an ultra-early-alpha-pre-pre-access-mega-beta thingy (I don't like that stuff), but there will be several playtest phases throughout the year.
The playtest is limited to 200 brave pizza delivery professionals, and 140 spots are already gone.
Don't wait until the pizza gets cold.
