No.  The A340-500/600 wing is not just a wing extension.  The simple
fact that the A340-500 is slightly larger than the A340-300 (318 pax
vs 295 pax in tri-class configuration) is because of the new wing
that Airbus has to plug additional frames in the center section.

>- where you got these figures (500M$ and 3B$)

Various reports.  With the definition of the B777-200X getting heavier
everyday, I think the $500M will be low for the -200X, but I doubt it
will go over $1B.  Just for a reference,  I believe the B777-300 cost
about $500M.

>- what would justify this difference (is the Trent 500 included ?)

No.  Engine development cost is not included.  With the heavier than
the orginal anticipated -200X, engine development cost for the
heavier -200X may be very similar to the cost to develop the Trent 500.
