But actually, Portal 2 might have a very benficial effect on FFXIV, or at the very least on it's forums. We can only hope.
Let's just say 20 hours, that's how long most people will probably play it for. Some will play it for 100 hours to get every last thing and complete every challenge 20 times but that's not the average user.

Even at 20 hours or more your argument still holds that it has little to no impact on the MMO market. Hell I'm going to play Portal 2 as well, between FFXIV sessions.
