Sorry, I haven't gotten to post on the forums in a while! After finalizing Zombies DLC, the team and I began reading the DLC feedback around the forums on the wants and desires. Guess what, level cap increase anyone? Got it and it's awesome. Hopefully we can get a full announcement out to you guys soon but, man is this the biggest DLC we have made. So don't worry, we are working really hard right now on both the update (that solves a bunch of issues) and the DLC. More to come guys!!
