I feel Square Enix, Capcom, and Konami are all in pretty different positions right now.
Square Enix: Square I feel is a mixed bag company. They used to be a top dog publisher, but now they're a company with a list of failures as long as their successes. However, what's key here is that they still have a notable number of successes. FFXIV and DQX are big earning services. Tomb Raider (6.5+ million) was a huge success. They have healthy mobile revenue and a good flagship in DQM:SL. Hitman (3.6+ million shipped) and Deus Ex (2.5+ million shipped) successfully relaunched both franchises. They've had success introducing new IPs like Sleeping Dogs and Bravely Default, even if they're not the same kind of earners as the others. DQ still performs strong with re-releases and spin-offs, and the next mainline will likely be a huge hit. Their remasters sell pretty well. There's a huge list of failures and a big list of addendums to the things I listed (Hitman lost money since those copies were overwhelmingly at $5-$10, FFXIV 1.0 was a catastrophic failure, their Japanese console development is in shambles), but they're a company that's having successes and releasing a fair number of relevant products in the market.
Capcom: I've talked about them at length, but basically I feel they're declining through having an increasing number of failures without new successes to counterbalance this, so their overall impact on the market is just going down and since their line-up isn't huge in the first place, that's a painful position to be in.
Konami: Konami is barely even a game publisher anymore. They have Metal Gear games that take the better part of forever to release, a sea of failed franchises, PES which is increasingly comical in terms of sales impact relative to FIFA, and a mobile department that has some successes, but has seen major hits fall by the wayside as the market transitioned from feature phones to smartphones. They're not even someone who comes up in the regular flow of conversation outside of Metal Gear anymore. This is definitely where Capcom doesn't want to end up.
If we include DA, DD sold 888k in JP. Even with the initial release it sold 609k in JP. That is absolutely massive for a new IP in Japan these days especially on consoles. With such impressive sales I would consider a sequel for it to be very likely........if it hadn't did so bad in the West.
I think Capcom failed at several things with marketing DD in the West. I remembering following the game and the only time gameplay was shown extensively were in these streams of poor quality. They didn't really release good trailers to capture interest. Furthermore, I have to admit DD is not a pretty game. In fact its quite ugly and the art style and area you are in is very generic. The real beauty of DD was its gameplay. I only got into the game after playing the demo.
I really really hope Capcom tries at least one more time with this franchise or even this idea for a game. Capcom must have so many amazing artists, so I hope if there is a sequel in the works they will create a more unique world with varying vistas and places to explore.
I think this is part of the core issue for Japanese console development. Even if you make something that is an astronomical hit at home, if it wasn't a really cheaply made game or also a notable hit abroad, it can't actually fund a series anymore. Given the taste divide between East and West, this causes a notable problem for consoles.
Now, assuming they want to continue, Capcom can view this first game as an investment and hope that they garner a better audience with the sequel, or they can try to make another entry in the series at notably lower cost.
So far we've seen them launch an expansion pack, a mobile/Vita f2p game, and Deep Down, which people thought might have been Dragon's Dogma 2 at first, but we found out it was a randomly generated f2p game. I will note that the way Deep Down is designed appears to be a way you can take concepts from a game like Dragon's Dogma and produce a much cheaper to develop product. Given that trifecta, I wonder if they're actually thinking of just taking the concepts that were successes and spreading them to cheaper products, while leaving "Dragon's Dogma 2" as an undeveloped game in case they ever decide to go back to the series as a major retail title at some unknown point in the future.
