I think we'll see a lot of fan-demanded male characters - Masque, Lodar and Vultak are pretty much guaranteed at this stage.
Mattel will reveal most - if not all - of the 2016 rebranded subscription.
We'll see very few female characters - and non-Horde POP females won't be represented at all.
New characters - NOTE: NOT 'SON OF HE-MAN' - will get a hefty boost. The Great Black Wizard, Skeleteen, the humanoid Battle Cat and Fang-Or. Females RoboWoman and Lady Slither might get some exposure.
