I don't think we gonna see a bigger wave like the last two years. The roster was so very much blown out of proportion back then still and they did trim down a lot... just look at the list of WWE Personnel. It's actually pretty slim, except for NXT maybe. Now, of course there'll probably be a couple of releases, but people shouldn't expect anything too big.
Shotzi, Ali, Gulak are three names that immediately come to my mind of possible releases. ... I wanted to add Cesaro to this list, because I didn't even know he already left.
