I doubt it but they seem to be introducing new 'characters' such as the dancing singing broadway woman advert and the new cowboy one. I dont know about Howard.
Thats probably because they stitched him up. Did you know they only paid him a one off fee to do all the adverts and he still can't afford to get on the property ladder!
Good looking guy like him should have no problem getting more advertising work! HaHaHa
