When it comes to things coming further than a week away from this leaker, it 's seemed like their source is the extremely early development phase - far enough away that things change. The Su-47 and Object 640 that they also leaked were hard denied, the latter by Bvvd himself !
It seems the same way here, that the info they got was perhaps that Gaijin was at one point conducting a feasibility study into paper tanks like the O-I and Lowe, obviously found them lacking, and plans to go no further in the pipeline w/ them ( like what the devs alluded to have happened to the Obj. 640 and it 's autoloader ). And likewise they might have brought up the need for a PR strategy against backlash for the Swiss → German ground subtree and/or a future wartime France location. But the very early nature of such things is obscured in the leakpost itself, to the detriment to it 's credibility.
2 major weapons like the SLAM ER and Taurus KEPD 350K wont make it better at CAS since f15E is missing some of the equals to that but I expect those to be skipped and put on f15EX instead
the only real change f15EX gets in ground and maybe except the pylons the ARMs which should be close to 2 which means it still wont near the f18E for ARM
