As far as the magic reveal is concerned, it can't happen until Arthur unites the kingdoms. If Arthur found out then Merlin would be exiled at the very least and he wouldn't be there to protect Arthur from the scheme that Morgana is inevitably plotting. The producers are never going to be able to please everyone and I don't think many people know how they're going to tie up all the loose ends but I'm sure they have a spectacular two-parter.
