Are you including fully-statted class variants from dragon mag like Wild Reaper Druid?
Wild Reaper (and come to think of it, the Urban Druid and some others) are in iffy territory since they're clearly shown as variants, but they tend to have enough changes that maybe being shown as a whole different class would work.
To head off something though, Psychic Rogue definitely gets its own entry because going from noncaster to functional caster is a huge thing, even if it's not a full progression.
I let Urban Druid get in because it changed the casting stat and put quite a different emphasis on the class's abilities to the point where its name could be changed to something more in line with city life (maybe Urban Savant or something, despite that already being a named class in Cityscape) and the only hints it might be similar to the actual druid would be an abstract concept of getting imbued with power based on the livelihood of one's surroundings, and a bit of shapchanging and a companion.
How I'll handle certain class variants is something I really need to think on now. I had intended to put them in the Dragon Mag ACF guide, but they could fit here too. Decisions, decisions...
