How many B744's w/ NEW Premium Economy seats???

I will be flying day after tomorow (Monday) on VS004 from JFK-LHR on the Boeing 747-400. After looking at the route map, the odds are that the plane will be "Mustang Sally" w/ V:Port (yes!) but , my question is: do all 744's with V:Por have the new PE seats? What are the odds that I will be in the new PE seats!
I know that theA340-600's have the new ones, right? and all of them have V:Port...
