Wynn after 34 classes split

Does anyone know how the choices for already awakened Wynns will work after the split into three new classes in Lindvior patch ?
Will we just be assigned the new "Wynn" class or can we make an active choice which way to go like Wynn Elemental,Wynn Spectral etc?

from the 3 other threads dedicated to the update i've gathered that no one really knows anything until they release the patch notes.
