Its highly likely we will be receiving buses from around the 2002/2003 time as Enfield's workshops are converting a few Volvos and DAFs as Tyresmoke has already confirmed and there's a Arriva Employee in London on Flickr called BristolRE who has posted photos from Enfield's workshops recently.
Someone wrote earlier that we could receive Presidents , There is a DAF President at the back of Ashington depot though its still in London spec so would imagine that's its not for use here
