I just hope your right JU.... (IRT AI subs and such).
The reason we all worry is from being somewhat burned in the past with rushed releases and things that are half done.
Again dont get me wrong. The Devs would love to put everything we are talking/dreaming of into a sub sim...but that would require a budget probably 100X greater than what they have to work with.
My main gripe is whatever they come up with...for heavens sake...PLEASE dont release it buggy as all get out. I mean OBVIOUS stuff like even after 1.5 came out... the helmsman still says "Rudder Rudder" when you command rudder amidships.
