18.104.22.168 equivalent. With torch god yes.
I would guess that true parity would come out sometime between December and Feburary of next year
After 1.4 releases on console, i would think that DR Studios will devote 2 weeks to a month to squashing bugs.
Then after that 1.4.1 and the non workshop things in 1.4.2 and 22.214.171.124 might come out to mobile and console, mobile first most likely.
That might take a while but because DR is super speedy, i would guess that it comes at latest at march
If crossplay comes, it could be a full year from that which, would not be ideal, but still be welcome.
(This is just speculation it hasnt been confirmed by DR or Relogic)
Yes, bug fixes will be a thing. You forgot Switch in your timeline there. Development, launch, and fixing for that as well.
