I've been on FFXIV since it came out, and even though I don't play it as much as I should, I'll still go back to it. I'm playing at least 3-4 other games besides ffXIV right now, and I *still* get on whenever I can.

So I don't think any new BIG game that comes out will suck people away from FFXIV for good. At least, not me ^^;

I should mention though that there is an upcoming MMO called Secret World which I'm eager to try..and even if it turns out to be the most fun thing ever, I'll still come back to XIV XD A mix of having awesome friends on it and the occasional new, fun patch keeps me playing 14.
