The Navy ships, RHIB's, helicopters could be referring to either Nautis (Former Ship Sim Pro 2.0), or Ship Simulator Extremes (abbreviated SSE, SSEX).
And those people on YouTube are either from VSTEP, Paradox Interactive, or copied the actual videos for themselves.
And the wait is only almost a month (August 24, 2010 Europe, August 27, 2010 U.S.A.)
