I personally would be willing to pay more money and wait longer if they were to make this game more true to the series. I would love to see the hand/walk/look/talk interface from KQV and KQVI as well as having a narrator for the additional interactions. Personally, it would not feel like a true KQ game without them.
The reason why I doubt they will have these features is cost. They are in the business of making money. So, why not pay more for a better game.
