Have there own program and inputs it seems unlikely for them to go all in just yet. They may have a set back in loss of F35 program tier status but they can still push hard to get those birds and likely will. Investing in SU57 will burn what F35 chances they have now. Besides that I suspect that Turkey wants total export control for any new program.
I agree that they still want the F-35. For one they already are manufacturing parts for it. For another I think they planned to purchase the F-35B for their carrier. It's not like the Russians had much of a good option for that. I mean the MiG-29K might work? But probably not with a runway that short. Besides it is older tech. Not to mention that they are still in NATO.
I agree that it is more likely they will go with someone else. Supposedly they are partnering with BAE but I wonder if they will be able to get that relation to stick given US attitudes against the Turks lately.
