No one knows what the theme of the next expansion will be.
False. NONE of the Tinker's abilities exist in the Engineering profession, and there are no abilities in the Engineering profession, only items and toys.
Um no. The Tinker is a WC3 hero unit and comes from the same source as the Monk, DK, and DH expansion classes. The Island Expedition teams contained abilities from HotS Tinkers, which again is another source of abilities and concepts for WoW classes (Demon Hunters took a lot of concepts and ideas from the HotS concept for example).
