Hopefully thismeans that the gameplay will undergo an extreme change; right down to its roots, it will be so vastly different that entire new tactics and modes of play will open up where they could not have before, so that even long time veterens will be taken back and have to relearn what they already know to adjust to the brand new playing field.

It does not mean, that they'll add more maps, twerk the sniper rifles and the IEDs and whatever just to make it a little bit different from the rest, as some narrow minded fans would have you believe. That kind of stuff can be implemented in updates and DLC, not a full game.
