I see a few different outcomes. 1) Runescape has everything people wanted, so people enjoy the game with no complaints. I find this very unlikely though. 2) It would also depend on how Jagex implements things. A simple example: People want the dragon pickaxe, and they get it. What matters now is whether it's useful or not. If the dragon pickaxe is nothing more then a for-show item, then some people would be disappointed and not use it, since it wouldn't be a good investment. If the pickaxe makes it much easier to mine, then a lot of people would find it useful. But then you have the issue of obtaining it. If it's very easy to obtain, then high level miners would complain that people have it easy, or about the fact that other items (Dragon axe) are more difficult to obtain, etc. If the pickaxe is hard to obtain, then those who can't obtain/afford it would complain about that... In short, it's impossible to please everyone. 3) People would get bored much quickly since everything is already there. First you'd try your idea of a new herblore system, then you'd go and try the new skills.. Go through any new dungeons you wanted, try a few new mini-games, explore new areas.. Finish those quests, play around with any new combat items.. Once you've finished it all, what's next? Everything is there, but you're bored and you don't want to play anymore. 4) Similar to 3, but the new updates spring new ideas to mind, and you want more :P.
