Regency Material

I am new to this game system as well as this list, AOL only recently adding
the INTERNET thing and all.  My primary interest in TNE is in the Regency
[for various reasons].  I was wondering, in the mass of books GDW is pumping
out for this system have they even bothered to include any more material on
the Regency than what's in TNE?  Is Norris still ArchDuke?  Did the Vargr
keep the territory they gained from MegaTraveller [I have the box set of that
one...yuck]?  Any new material at all?
