Aircraft for VS029

Hey All,
I hope you can help, I keep on finding conflicting information regarding what aircraft I will be on a flight to Barbados. I can see from your tools that G-VFAB is the aircraft use most of the time however Wednesday seem to be a bit of an odd day and that is the day I am flying.
I can see from my booking pages that the plane has Seat Configuration 1. However on the Virgin Website it says all 747 aircrafts will be Seat Configuration 4 after March 2010.
So is it just the case that the booking website is wrong? I fly out on the 30th June.
Thanks for your help.
