5e can have the prestige classes that 3e intended to have.
First, lets talk about what PrC's were kind of supposed to be in their original concept: classes that you entered in at higher level, that represented secret knowledge, advanced skills, or some other quality that could only be learned by certain people. They were intended to give flavor and dimension to a campaign setting by fleshing out groups of powerful people that adventurers could join or fight against, and to represent "Advanced" arts or specialized mechanics that adventurers could learn.
There is *totally* still space for that.
Some 3e PrC's more correctly represent something you do or want to do from an early level. Most of their "mutliclass capstone" classes fell into this role, but even things like, say, Arcane Archer could conceivably things you do at the start of your career. These things are probably good fits for subclasses.
Some 3e PrC's also focused on fairly limited mechanical schticks rather than any sort of archetype or identity. Arcane Archer is another good icon for that, but so is, for instance, almost any 3-level PrC, or most 4e Paragon Paths. These things are probably better fits for 5e feats, big as they are.
But there is also a pile of things out there that would still make good PrC's in 5e, as they do fit the mold of advanced knowledge or specialized abilities or specific elite organizations.
The thing to realize about what might make a good actual PrC in 5e is the word prestige. If it's not a symbol of elite lore or knowledge, it's probably not something that needs stringent, higher-level requirements to qualify for, so it's probably better off being a feat or a subclass.
And given that 5e is presumably grabbing 3e's fast-n-loose multiclassing, it'd be very easy to institute them, even if WotC does not.
