Mark my words, in 2030 there will be 3 great powers.
1. USA
2. China
3. Turkiye
However, a lot of work still needs to be done. For one, the integration of Turkiye and Azerbaijan must reach a confederate level with the establishment of a direct border link. All Turkic states must integrate...
I am not saying they will place a 100-200 order tomorrow. However, over the timespan of the partnership they will operate TF-X in that magnitude. Remember, KSA wants to keep a strong air force with many 5th gen fighters and they are not getting that from the US.
There was a very high level Saudi delegation visiting. Negotiations must be in an advance stage before Turkiye shows the aircraft to KSA. KSA could become a (financial partner) ordering 100-200 TF-X. If true, it would solve one of the main non-technical hurdles for TF-X i.e. economic viability.
