So historically expansions have followed a trend of 2 races, class, 2 races, class (and race). Assuming this trend holds, we're due for a 2 class expansion next.
And since there's been discussion for weeks about what class, or what we want from new models, maybe we should focus on the new races for a moment.
Traditionally, 2 races mean one for Alliance and one for Horde. However, with the new Neutral Race tech, could Blizz blow our minds and introduce 2 neutral races instead? Or could Blizz use new models as an excuse to only add one Neutral Race?
