Seat selection maps.

Quick question, hopefully quick answer.
I'm on a VS45 out and VS2 back in a couple of weeks. Both A340-600s. I saw from another thread one V-flyer has just started that exact trip!
My question is this: Are the greyed-out seats on the seat selection map all actually taken seats?
For instance on the way out every A-seat bar one is taken, and 5 K seats remain. Only two Ds and one G are taken.
Do people prefer A? Its not like many are trying to sit opposite each other with only 3 D/G's gone.
VS2 on the way home looks dead quiet - 10 seats taken (although there's still time yet). No middle seats taken, but again why has someone selected 17K when 30 other seats are available?
My first time on Virgin in about 5 years. Excited...
