Replica is slowly coming into the light in the form of the Turkish T-FX it seems:

The image shown is apparently that of a BAE model displayed on their stand this week (as oppose to the RCS test model we have seen)
It is still upside down, but if nothing else, the image is from a new angle as far as I can tell and despite the press embargo in the UK (due to the impending election), the suggestion is that the T-FX could represent a future project for the RAF as much as Turkey.
