From the article, "Et tu, Deep Down? No, that’s wrong. The game isn’t the one to blame. It’s just a game. It’s Capcom that has let me down with Deep Down, though I guess I shouldn’t be surprised. I got my expectations up and hoped for a Dragon’s Dogma successor. Capcom’s usually all about getting as much money as it can out of its customers, and making Deep Down an offline, Dragon’s Dogma successor probably wouldn’t be as profitable as the reveal that it is now an online RPG."

Former Sony executive Shawn Layden has "no idea" what happened to Capcom Deep Down game, which disappeared after announcement.
Still sucks we haven't heard much from it. Really liked the concept behind it, and I feel like I was one of the very few who liked the game's music. A shame it's in hiatus as of now.
I think Platinum has been overextending itself for a good while now. Scalebound was canceled after missing deadlines and Bayonetta 3 has shown nothing since its announcement in 2017.
While the game never came out, I don't think it was time wasted. If you look well at how the camera follows the character and how it moves around during "gameplay", you'll notice it's spot-on identical to the camera in Resident Evil 2 Remake. Deep Down might have been cancelled, but it most likely became a proof of concept for Capcom in development of the REngine.

Don’t count this game out just yet. Are we going to see Deep Down release on PS5?
Hopefully its still in development and will be released on ps5 because deep down trailer looked amazing when showed years ago
Hopefully it maintains the technology (like their fluid/particle simulations) and 4 player co-op

Here are 10 major video games that are missing in action from the public eye, and we hope to see them make a triumphant return in 2020.
To early to tell all of the details and how it will play out.
People need more patience and withhold so much judgment until we have a relatively clear idea of how it will play out.
C'mon man, 20 second teaser and we're all let down now? Let's just wait till tgs'13 and then we'll talk.
What worries me is that people have the balls to complain about something when they know next to nothing about it. Yeah, Capcom has a bad history, but let's wait until we get more information before the whining hits fever pitch.
Teaser doesn't look good . But E3 trailer was awesome. If they don't deliver something near E3 trailer i would be disappointed too .
It kinda sucks ,online only :( well at least we still got The Witcher 3 and DS II to look forward to.
