WrongIf they sign deal early next year, the jets won't arrive before 2030. (For comparison Qatar signed the deal in 2017, their first delivery was in 2022.) Not to mention Spain, Italy and Germany has already placed orders for new batches.
The EF that Turkey would buy, at least the first 20, would be given from the inventory of the British Air Force. The British Air Force wants to retire their tranche 3 fighters but as they are in good condition with lots of life service left, they are opting to sell it to Turkey with the topping being complete transfer of the computer's mission/software codes so that Turkey can integrate whatever they want on it
Therefore, if a deal is signed early next year, Turkey may receive the EF jets by the end of the same year
