The severity of a wake vortex is a direct function of the weight (and
therefore lift) of an aircraft.  Yes, a very very heavy 747-600 or an
A340-600X will probably generate a bigger vortex pattern than a 747-400
or an A340-300, and yes, they may have to increase following distances
accordingly.  Then again, the physics of the designs may make them no
worse than current generation aircraft.  That's why they test that sort
of thing on the computer (using CFD) and in real life (usually at
Atlantic City Technical Center) just to be sure.
