Sorry if some/all of these are old (I know COD Ghosts is, but it's here for completion's sake) - they're all courtesy of Zavvi. I'll post only the ones that I think may be final artwork, the rest will be at the link at the bottom.
The following have "Provisional" under the PEGI rating, but I assume that relates to the rating itself - not the boxart - as some other games have "Final artwork coming soon!" on them. I am assuming those are the ones without final artwork.
All games - some (maybe all, who knows!) with non-final box art
