Not being included in SL prtty much shot down the chance for both dr and necro becoming a class, at least anytime soon. Bard, There just isn't enough bard lore in warcraft to justify them as a class, at least not before the others mentioned, imo at least.
So that just leaves those 2 left. Dragonsworn and the 5 flights have covenants 2.0 written all over them. So by process of elimination that just leaves us with Tinker unless Blizzard completely abandons the covenant style system.
