It was a strong rumour, now confirmed by R. Chung, the Kinetic boss himself, in ARC forums. After the Sea Harrier FRS.1 (link) & FA.2 (link), the two seat Harrier T.2/T.4/T.8 (link), Kinetic is quite logically to produce 1/48th Hawker Siddeley/BAe Harrier GR.1/GR.3 kits.
So time to open a dedicated thread, I think.
