Please again calm down ... nothing hints towards being ready and all what is shown is a diagram that looks in no way of what we expect from the WS-15 - aka TVC and serrated nozzles - and rhe real engine shown is clearly a F135.
So whatin your opinion tells you the WS-15 should be ready?
Quite a lot of differences between it and the EJ200. Length of certain sections and comparative changes in thicknesses. Even the sections seem like they have different compositions and lengths. If not the actual WS-15 or WS-19, at least that drawing is a unique side view of some low bypass turbofan.
