Uh, why not?
Well, because it just sounds a bit too unreal for Konami to do. I'd rather they come up with a good new tactical battle system, that has a few of the same classic elements from the previous games as well. Having all those options for a single game would just be asking for too much.
I just don't like it when people demand and state things so quickly without considering, how much they are insignificant towards the production and making of the game compared to the actual development team. It's the developers that make choices on all these things, and I support them all the way. They work hard, I don't like being picky with their beautiful creations. It is made through their eyes, not ours. I wish we could all just respect that a little more and not demand so much. I am not saying EVERYONE here is that way, it's just a few posts that caught my eye.
