Sounds cool. A little more variety with Controllers would be nice, as we only got one so far. As for the Psionic Controller, that'll probably be the Psion (They may change the name, but personally, I like it).
Anyway, has there been any indication as to how many pages the PHB II will be? I ask because, while the PHB I has eight classes, the PHB II may have more then that if it's got the same page count. The PHB I has dozens of pages devoted to equipment lists, skills, feats, and game rules. The PHB II will probably have some equipment and feats, but it's doubtful that it'll eat up as many pages as the PHB I counterparts. We probably won't get any new skills, and there's no need to repeat the rules in the PHB II. In which case, all that excess space can be used for classes, instead.
So assuming a 320-page PHB II, it may be possible to pack in 10, or even 12 classes. Boy, I hope so, cause that'd be great. You could stick in the Barbarian, Bard, Druid, Illusionist, Monk, Necromancer, Psion, Psychic Warrior, Sorcerer, and Swordmage, and probably still have enough room left over to stick in another class or two (Maybe a Samurai [Ki Defender] and the aformentioned Divine Controller?). Well, we'll see.
