Yeah, it is. A while ago, it was teased with a license plate called "BNG 27" indicating that it's meant for the 0.27 update. Also, with how much it's being teased right now by the devs, it'd seem quite odd to then not release it in 0.27.
If it won't be available in vanilla, I'm more than sure it will be modded in. I mean, there's one dude making a soviet sedan out of the Miramar.
A question, I'm making a cinematic scene, but I can't finish it today, I can only do it tomorrow, but would it be possible to make Steam not update my game so I can finish making the scene in 0.26? (If not, I can do the scene again in 0.27 but I would like to know)
Yes, you turn Wi-Fi off, then open steam, and it should give you an option to go into offline mode. You could also set BeamNG 0.26.2 as a bookmark, which adds it to the Windows bar at the bottom of the screen, and it never requires updates, that way, you can leave Wi-Fi on.
Most likely around 7:00-8:00 AM East Coast time because it usually releases at 1:00-2:00 PM German time
Guys i have to honestly tell ya all: If this is not gonna release todoay im gonna lose my sanity. Gonna revved myself up waaaaaayy too much this time.
