Found this on the Dev tracker

"We know you're all very interested to hear about how the new level cap is going to affect your class, and I wanted to share a little information about the upcoming changes with you. As part of the new content, every skill tree will be expanding and you can expect significant updates. Players will earn a new skill point with each level, and new skills will be available in each skill tree. Additionally, a new active ability will be introduced for each Advanced Class. We'll have more details about many aspects of Rise of the Hutt Cartel as we approach launch, so keep your eyes on the website and dev tracker!"
