Not all of them, some of them do, though.
Some of them make a return in a different form. For example, the Exp. Share which was once an item, is now a Key Item.
Same with the gems - the Normal Gem is existent, but no one has seen any of the other gems, so it's rumoured they don't exist.
I'd recommend just asking which ones you want to know and what their status is.
Hope I helped. :)
