Definitely gone, although who's to say it won't come back? There was a really foray of activity in the white chocolate version market a while ago which was great because my husband is allergic to cocoa (not chocolate, just the powdery brown stuff). White chocolate twixes were really nice but I haven't seen them for ages and I always look thoroughly at every sweet counter I go to for any white chocolate versions. I haven't seen white kitkats for ages either or white digestives or white hobnobs. You can still get white Maltesers, they seem to be staying.
