Small chance that it will happen on June 8th, but I am thinking that it will likely more or less happen with the release of the 313
Adam said so on the roadmap stream a couple of ones back. That the plan is to release the East Costway PIS when they release the 313.
If you mean "when can we see the PIS in action", look at the last challenge stream because Adam ran a dev build with the PIS active on that route. If you mean "when is it being released" I haven't seen a confirmed date
Nobody knows. Guesses masquerading as statements of fact don’t help anyone. If some asks if anybody knows the date and then you give a date it implies that you know. Then when asked where you got the information from and you reply it was just a guess that indicates that you should not have answered the question in the first place. If it’s a guess, say it’s a guess when you post the date.
