Personally, and I haven't read all the other responses yet, I don't care how many classes there are or aren't, or what is or isn't a class. The important thing to me is character concepts and being able to effectively reflect them in the game. Whether that means that the traditional paladin is some package of (multi)class-theme-bg or is its own class is irrelevant to me. They should do whatever works best to reflect the traditional roles, and maybe open up new ones. I know that they said you could make any class that appeared in a PHB1, but I would count that fulfilled if say Druid was a package of cleric-theme-bg. I feel like some of the traditional classes carry a lot of the RP weight that will/should be carried by BG and Specialty, so it would be sensible to split them off into combos.
I think this might help ease multiclassing headaches as well. If a Paladin is a Fighter+Priest+Crusader, then you could also have a "Pala-wizard" by doing Wizard+Priest+Crusader. So, from a story perspective, you have to ask "Does this traditional class have enough room for TC+Slayers and TC+Healers?"
Mechanically, I suspect that it will be fairly easy to crank out classes with unique mechanics, so I don't think that's going to be an issue. Making them fit the inherent story/vision of a traditional class might be harder, though. I still suspect that we will see (eventually) a splat-blizzard of new/recycled classes, backgrounds, and specialties.
