I'm not even talking about splats. Look at 3.5 core. It is entirely more versatile than 4e has - thus far - shown itself to be.
Look at the warlord, as has been mentioned. All melee. You can't make a ranged warlord. Multiclassing doesn't solve the problem, either. Is it possible that there are some feats, or whatnot, to make it marginally possible? Sure. But from what we've seen, the warlord is all melee, all the time.
Now look at any 3.5 class. Does it tell you that you must be ranged, or that you must be melee? Does it tell you you have to take one particular approach to the class? No, it doesn't.
4e classes are archetypes, and I sincerely doubt that that's going to go away, because that seems to be how they're approaching class design nowadays.
