Capcom V.P. Christian Svensson added a note about the success of HD Remixed titles and having the right franchise to couple with them, he also fielded a Final Fight question in the process, via the Unity Boards.
What are chances of Capcom making a Final Fight HD Remix, based on the original game? With support to 3 players online co-op... — Digão
Sven: I'm not so sure about an HD Remix for Final Fight being completely viable (HD Remixes are VERY expensive), but we may be able to help you get your fix somewhere down the road. I don't know, we'll see.
Have the HD Remixes Capcom released so far been successful?
Sven: They've all been successful... but we've been judicious in their application and we've been adding features pretty much every iteration. It doesn't mean every franchise would be successful following the same plan. Execution is part of it, the other is having the right brand to apply them to.
It's interesting that all of Capcom's HD Remixed titles to date have been successful, but they still don't want to do it for all of their re-releases, because of how costly the process is.
Makes you wonder which franchises of theirs will get this treatment though.
