I'll probably do something for it once we get more gameplay demo, but here's the short of my opinion. While they could theoretically made it all DLC, I think that they're adding in enought content to more than justify a sequel. There's almost doubling the amount of classes, and there adding in a whole bunch of new modes, too.

I mean, think about what they'll have to do for all this. They'll have to make models for all the new classes, Weeds, and Zombots. They'll have to configure AI for offline play. The amount of maps would double. And that's just the beginning. They probably never designed the game to get more classes, just more variants. So, they'll have to re-code the game to accept entirely new ones.

At some point, it just becomes simpler to make a whole new game and incorporate these things from the get-go. And while the concern of them pumping out a new GW every year ala Call of Duty does exist, they seem to be adding in plenty of new content into this one to warrant a whole new game.
