This RE6 sold more copies than RE7 but RE7 cost way less money to make and when you adjust cost to profits they probably were close to even. Since a low cost to make is a safer bet to risk averse businesses 7 won out in the end.

Survival horror was seen as fad because of the under performance of REmake,0,outbreak1/2,CVX and Dead Aim. Whether or not each of those game under performed solely because horror wasn't that popular is debatable but it wasn't as popular as shooters. Action was big and always has been but if everyone is making action shooters, it's hard to stand out with an action shooter.
