I very much doubt it. Pretty much all of the most requested packs at the moment are game packs so I don't see them ditching them. (hotels, bands, fairies, werewolves are all most likely game packs, generations is the only highly requested pack which is without question a full EP)
And recently they've also started to shrink packs to kits and stuff packs so they can get requested themes out without making it a full pack (Moroccan furniture kit rather than a full Moroccan world adventures type pack, Paranormal stuff rather than a full supernatural pack, Indian fashion kit rather than an Indian themed pack, etc etc) so I don't see them getting rid of the "middle" pack type at all.
