I cant see the cash strapped RAF "adopting" the Vulcan for the BBMF, think there are a few front line assets that require the money more so, although i would expect to see the Vulcan "formate" with the Lancaster, well that is if the powers that be allow it. Those high up always didn't want the fighters to participate in anything other than their own routine at shows like Legends, but I'm glad to say a relaxing of restrictions now allows them to take part in some of the scenarios there.
What is needed is a big generous sponsor who doesn't mind not having their logo emblazoned across the aircraft, part of the criteria from the lottery was that the aircraft has to stay in its camouflage livery. As marketing goes I cant see anyone really taking that up, its alright being called the 'Red Bull Vulcan' but the Red Bull livery Vixen was a much better way of getting the product out there. On that subject I hear the Vixen may have a new aviation related sponsor for 2008 
Good luck to the Vulcan but its going to need someone with very deep pockets....
