I don't think anybody can give an exact date.  I don't know about Captain Sim,
but I think a lot of developers have "other" full time jobs and only work on
Flight Sim products in their spare time.  I also think different parts are farmed
out to different people.  So, it's anybodys guess as to when a product will be
finished?  I might be wrong?

One thing is for certain.  A B-52 from Captain Sim WILL be worth waiting for.
