There are currently 8 A380s and 8 787s due to be in service by the end of 2014.
BA have said they are standing down 9 744s and the 7 long haul 767s that have not been refurbished by the end of 2014 which ties in with the new deliveries. The remaining long haul 767s will be gone by end of 2015.
Historically when BA have stood down aircraft they have not always been immediately sold or scrapped. I would expect at least a few to remain parked up at CWL or LHR as spares and to be salvaged for spares!
