Prestige classes was a phenomenon that built over time. When 3e was released, PCs took no time because there weren't any (DMG list excepted). You didn't have to sweat meeting 3 different sets of PC prereqs by lvl 10.
4e doesn't have splat books yet. UNLESS there is no mechanic equivalent to PCs (and we all know how much players like options, so odds are good such a mechanic will be introduced if it doesn't exist already) introduced in the splatbooks (which we know are coming), you cannot discuss prestige classes in NPC generation times without being grossly unfair to 3e. Apples and oranges.
