I'd like to think that any room full of idiots can put together something moderately horror themed. Not to say that Capcom are idiots - and as a company they've actually managed to do it before, so they are ahead of the curve here.
They just have to try. If they put their actual focus into horror-themes again it would work. But it can't be an action-shooter with occasional nods to horror elements. And it can't be a dark game starring a gun-toting, catch-phrasing, melee-comboing action hero.
It has to be all or nothing for them to succeed again.
