Er, this isn't exactly news.
ED have been doing an F-16 on the backburner for years, as shown by the renders they shared of their in-dev 3d model ~4 years ago.
When pressed recently, Wags has said "when, not if".
All that probably happening is now is that after various features have been added to DCS for the F/A-18, they're looking at it coming off the backburner.
It'll probably still be at least 2 or 3 years away before it gets announced properly.
