As far as I am aware (and from the info on the BA site) the CW product doesn't look to be too much different from the existing one. In my opinion the seats in F on the existing fleet will be better than the CW seats on the A380 (this assumes you don't end up with OF or even a damaged / dirty seat in NF - see threads passim).
Howevert here may be something special in being one of the first on a new aircraft type..
