Metal Gear: Rising Sun - Have They Ruined Metal Gear?

From what I've seen and heard it does not seem like a typical Metal Gear, in truth I would be most happy if they reverted back to the playing style of the first and second, preferably second so you could still have the first person shooting view pegged in!

I am not and in truth never have been a major fan of the camo system in number 3 or 4 but went with it as I love Metal Gear, but the more and more "Advanced" changes in the games have ruined the experience for me somewhat and now this seems like an almost completely different game, so question to you guys... Have they ruined it? Or have they done a stroke of genius?

To be fair I know the game isn't out yet so it's still a tad difficult to say.
