I'm curious to know when they're gonna announce the last character as well. I agree with JayShadow about the online challenges being reasonable places for an announcement on that.
I shouldn't jump the gun this way, but really what I'd like to know is whether or not there will be a third season of DLC, given the financial struggles caused by the coronavirus lately. I hope we get a third season!!!
Do we have any hard data on sales, whereby we'd know how well season 2 has been selling?
No, unfortunately we don't have anything even remotely resembling first-party sales data (Namco rarely discloses such information on their titles during the sales life of a game--and indeed, this is an increasingly strong (though not ubiquitous) trend amongst publishers generally these days, where the game is not a pure platinum game take the industry by storm. All we have are some indirect measures and a whole lot of conjecture (which in this particular community tends to lean into optimism disconnected from any real evidence. We do of course know that the game was at least marginally successful enough to warrant a second season pass, but I'm not sure this tells us a whole lot, since 1) they make a larger proportion of net profit relative to cost of production on DLC, making it tempting to go out on a limb in such circumstances even when the install base for the peripheral software product is not huge, and 2) Namco, and all producers of fighting games, are clearly keen to seize this moment to establish the multiple season pass/continuing support model as the default for their games in this genre, so they might have invested in the second season pass even if it was going to show incredibly minimal profit (bearing in mind this decision was likely made at least a year before the pandemic).
As for prognostication, I remain cautiously optimistic. There is some cause for concern: most people, particularly in western markets, are oblivious to (or in deep denial about) just how bad the coming recession is going to be, but a company of the scale of Namco will not be, and may be planning on curtailing production somewhat. On the other hand, the gaming industry has (so far) proven to be somewhat resistant to the effects of that recession because of the obvious boost (at least initially) that results from people staying home. Now that is in all likelihood a sales bubble (no matter how bored they are at home, people cannot spend money they don't have if the recession hits hard, as it certainly will eventually), but it may still embolden companies enough to proceed with planned projects for now--particularly those which have already consumed some degree of development cost. Of course, we don't even know that Season 3 was planned at any point, let alone that initial design and development were/are under way, but I suspect at least some basic outlining had taken place even before the beginning of the pandemic. And then there's the fact that, as mentioned previously, a season pass has certain advantages in the profit-to-cost ratio (assuming there is enough buy-in, which does tend to tapper off the more DLC is available under the core product license--one assumes particularly so with an experimental new model).
Still, all factors taken together, I do think we're going to see a Season 3. But I wouldn't rate my confidence level as high.
