So, according to that there are about 144 aprox. spells, inlcuding "sub-spells" as the announcement does count.

Out of all of them, only 4 are Divination Spells for wizard, which is pretty underwhelming and make me wonder even more which Divination spell will they include in order to make the Divination Wizard viable.
