To me, the whole point of the bard is its flavor and function in the narrative. Who and what a bard is is significantly different than clerics, wizards, and the like. And as someone who thinks they have some of the most interesting flavor of all the classes (I will always contend that 2E's Complete Book of Bards had the most engaging and widespread variance of kits than any of the other books)... their mechanical functionality doesn't really matter. Whether they are full casters, half casters, three-quarter, one-third, non-caster or whatever they get placed as... WotC could choose one of them randomly and build a balanced mechanical display and it wouldn't affect the bard narratively at all.
So at the end of the day... I am quite happy with whatever form it ends up taking, so far as it remains in the game.
