The Coretex Design company broke some years ago and team dissolve (some build Polychop, others as me, continue on solitary) and we never get a functional ground radar or other complex system to a reach never to a stable "module" to release into DCS: W. The best options has other team intent first get a LM / F/A-18E legal license and build a stable team to get the SDK and 3rd party status by ED and start work from zero, not dream with a doom project with never reach a milestone.
The only "news" about a F-4E has a new AI 3d model, but ED, BSK or none 3rd party has "confirm" a F-4E develop, some talk about legal issues and license problems, similar to the A-4 (Veao intent get the license and the cost to get them was prohibitive, drop the project).
About the Aviodev F-1 not more news has deploy about them (I think actualy has "on Hold"). The Veao Thypoon has actuly a military contract to a DDT (Desktop Trainer) to the RAF, not detail news has get by VEAO (by the NDA military contract), but he planed build a Block IB, meanwhile, continue waiting to some news about them.
