I wrote a wall of text on this topic the other day, but I’m going to paraphrase and remix myself:

MMO Players are highly tolerant of launch problems. Some will shout and cry, others may declare them features, still others may skip launch altogether or leave and resample the game later.

They will still play.

In the end, the game will be received on its merits and the launch issues a fading memory, having as much relevance as anything else you no longer experience. Nostalgia will even set in for some bugs.
