…and don’t forget medierra’s recent comment on the topic either:
I’d do a 3rd expansion if there weren’t so many logistical / technical issues. Based on FG sales, it definitely seems like it would be financially worthwhile. The problem is, the way certain systems work and the way we designed some things, each expansion becomes exponentially more challenging and burdened by the interaction with existing content. Adding more can also inadvertently detract from the existing game - it’s already hard to find the gear you want for your build, due to all the different types of gear, number of damage types and amount of class or skill-specific bonuses. Adding even moar on top of that will only exacerbate the problem. To resolve that problem, we’d need to create a new loot / drop system that could tailor drops to your build to some degree… but that’s easier said then done with our class / item system. The flexibility people have in creating builds would be a hurdle in trying to create any sort of tailored drop system… and then, the amount of work that entails and which would be needed to update other systems, makes me feel like the effort would be better spent on GD2, then trying to overhaul the whole game.
If it were just adding story content, that’s a little more feasible but hard to say whether some sort of DLC that was just story / levels without new classes and such would sell that well. I imagine hardcore fans would buy it but it would still be a lot of work and unless it has some wider appeal, I don’t know if it would be financially viable. I think a big issue too is that it would have to be more side content and not content that increased level cap, which I think would put a lot of people off.
A 3rd expac is not looking likely at all.
