I can see the current hiscores turning into 'lifetime hiscores' instead of 'old hiscores' but there probably won't be more changes to the system.
As for you quitting, assuming you actually do quit and don't go like let's give this a try like most players will say on release, or rage for 2 months then come back, that is sad but you just happen to be one person.
One person quitting every so many that aren't doesn't make a difference. If just one of all those players who aren't going to quit now, but are going to quit eventually, stays around for one more month because of prestige, the update is a success.
