Stuff is up for pre-order. Looks like the ogers get no endless spells. Which is odd.
Also, some models have slightly updated rules for the ogers. The tyrant for example has a better loadout.
Not all the warscroll pdf's currently work though so that's annoying.
The endless spells for the bonepeople aren't too terribly overpowered. Though their basic unit the morterk guard is super freaking powerfull. With 1 wound, 4+ save, rerolling failures, and their weapons having 1" 2/3+/4+/-1/1 or 2" 2/3+4+/-/1 scoring 2 hits on a unmodified hit roll of 6 and they can have a greatweapon for 1" 2/3+/3+/-1/1 (no bonus hits on that one though). They are insanely powerfull imho.
O and the luitanent needed to do their command ability is indeed their equivalent of the alpha model. Making the range requirement largely redundant. Though at least not every unit has one of these, for example the 4-armed guys (necropolis stalkers) don't have an alpha.
