Here is their description.
New Moves PackThis is one of those deals where I don't know if it's must-have, but you kind of get into that situation where you think, "It's only $3.99 so why not?" I'll probably get it. That Sister Abigail sounds pretty cool for one.
Moves Pack: More than 30 new moves, including an alternate version of Sister Abigail (performed from the ring corner and made popular by Bray Wyatt®) and Multiple Gut Wrenches (made popular by Cesaro®); The New Moves Pack will be available in early 2015 for a suggested price of $3.99.
WWE Games has promised a full list of moves shortly.
UPDATE: Here's the list from WWE.com.
