Welcome back. Right now you're in the middle of the Brand Split, so there's a fuckton of new championships.

The current champions are:

WWE Championship (Smackdown): AJ Styles (Weird, huh?)

Universal Championship (Raw's main championship): Roman Reigns. (The more things change...)

Intercontinental Championship (RAW): Seth Rollins

United States Championship (Smackdown): Shinsuke Nakamura

Raw Women's: Ronda Rousey

Smackdown Women's: Becky Lynch

Raw Tag Team: Drew McIntyre and Dolph Ziggler

Smackdown Tag Team: (And still,) The New Day.

Cruiserweight Championship: Buddy "The better half of Blake and" Murphy

There's been a lot of new additions to the roster, a lot of things to get tired of, and an entire Brock Lesnar title run to just ignore. Just watch NXT and Smackdown and maybe RAW if you're interested in any of the people. And 205Live is a must see to most people.
