Geez, give them a break. Jet Thunder is a complex simulation and will take time to develop. Just like Cliffs of Dover. Just like DCS:A-10C.

Don't assume they're not working their asses off just because <*gasp!*> you don't get screenshots every week. It will be released, but until then there's no point in showing off half-baked features and describing incomplete code. It only sets the wrong expectations and shines a bad light on Work In Progress.

Don't know who decided to announce those ridiculous release dates, but it looks like they've learned their lesson.
