Ohh boy, ohh boy. DCS is in for rough times and even more delays.
As I can not view the link, does this mean the main DCS devs are working on it? If so, I hope it does not delay the Su-27 flight model and MiG-29/Su-33 updates. Or any of the other modern stuff...
And this is the second project to have issues (first being MiG-21) which is not a good way to start. At least Belsimtek seems to be able to deliver.
