Okay, I shouldn't, but for anyone curious here's the story of what happened to Deep Down. The game is over five years old now, maybe it's a good time for this to come out publicly.
Deep Down was a sinkhole for Capcom. That announcement trailer? It was fucking bullshit, at the time the engine could only run 2-8 FPS, how that trailer was made was they took fucking screenshots of the game and turned it into footage and did the sound for it, I'm not fucking kidding. Even once the engine got off the ground to be more functioning, the game would still only run around 5-25 frames per second. The engine could produce some good visuals, but it ran like ASS. More so, what was completed for the project simply was NOT FUN, everyone who ever got to try it realized the game was not coming together. On top of this, the Phanta Rei Engine, which internally was known as the Sophia Engine, was really hard to work with. It had terrible user interface and was very unintuitive and a chore to use.
Capcom sank so much time and money into it, but ultimately realized it was a failing project. All of the people working on it one day were told to just stop, the game was sent to another segment of Capcom to try and 'save' the project, port it to the Unreal Engine.... and it was never officially cancelled, but it kinda' just silently died. Many people within the company don't even know what happened to it or where it currently is, it's probably in some Capcom storage basement somewhere.
Ono has lost a lot of power within the company so he likely won't be able to bring it back, plus it was a financial disaster for them and the much, much, MUCH better RE Engine came from the ashes of the Phanta Rei/Sophia Engine, so unless Capcom decide to remake it from the ground up one day, it'll probably never see the light of day. The actual Deep Down people know ran like shit and was not fun, and it kinda' just disappeared when being ported to the Unreal Engine, end of story.
