From Classics Hangar's forum (I hope you don't mind Mathias!)
"We heard from reliable sources that the mystery aircraft is currently being prepared for combat trials.
The source claims that several of the above aircraft are being prepared with camo and unit markings so we expect them to appear in larger numbers soon.
In the meantime we received a photograph captured by a B-17 tailgunner of another as of yet unknown German fighter aircraft that dived from very high altitude on the bomber stream"
So is it a Fw-190D (previous pic) AND a TA-152 or just one or something else???
Exciting stuff !!
