The ATS crew of SCS had a big streaming event (I will post it when it's on Youtube) and they hinted... pretty much stated that several new trucks are coming to ATS soon. Pavel was very generous with info in this stream including this reveal of an upcoming truck, which shocked everyone...
It is an older International 9900i Eagle. They said this truck is in a "Fairly advanced state" in terms of development for the game. They also didn't rule out the Western Star 5700XE. They said they were working on "Various trucks" for ATS and to let our minds wander. There was no limitations. There was also confirmation that they have the sound for the new Volvo VNL, but nothing else was said.
There were more teases about a trailer manufacturer coming to ATS as well.
Also new locations are being added to Wyoming such as Cody and US-14. More indepth Yellowstone will be in the game based off these screens from the stream. Upon this completion, Wyoming will be the most "complete" state in terms of major roads and routes within the game.
PostEd truck has a new design. Not as similar as FedEx anymore.
This is not an official image, but it should something roughly like this.
For ETS we got this quick image, which is the interior of a MAN TGX.
