Uh-huh. It also had Speciality Priests, and Speciality Wizards, neither of which is present in 4E, and importantly, 4E doesn't have Druids or Bards in the core books. It also had, as I recall (perhaps inaccurately) more description of each class. Still, that's 20 years ago, Mourn. What's more relevant is 3E, and politician-style, you avoided mentioning that because it doesn't support your point.
3E had Barbarian, Bard, Cleric, Druid, Fighter, Monk, Paladin, Ranger, Rogue, Sorcerer and Wizard, and had specialization for Wizards and some limited specialization for Clerics. So, 11 classes there. Maybe you should argue that they had less meaningful options or something instead? 7 races, too.
I'm not attacking 4E, but I think my points are valid. Thinking about it - 4E does have a "lot" of one thing missing from the 3E books - Decent advice/guidelines for players, and decent advice (but not guidelines) for GMs. There's certainly plenty of things that I expected to be in a DMG that simply weren't there though, not least the complete lack of advice on designing powers, classes or races. If they break that advice up over 3 DMGs, I am NOT going to be happy with them.
