Iterations are going to roll out on a weekly basis. It’s likely that we are receiving new double barreled vehicles next week (why not now who knows).
Amongst other things and the listed 1st iteration “credits for directives” test, WG is preparing to release a lot of 3D styles for these vehicles: Object 907, FV4005 Stage II, Progetto M40 mod. 65, T-100 LT, Object 430U, SU-130PM.
