On the elder scrolls official site has been told that they WILL ask monthly after 1 month free trial. But they're still discussing the exact price.
And speedy, there's no way to possibly change the total gameline at this stage. They can make the gameplay with the character a little more comfortable and they can fix all bugs, but not all the quests,...
This is almost how it will be with its release. I've played it a little longer after I made my opinion here, it became a little less boring, but I'm still not convinced.. maybe I'm expecting to much after the awesome skyrim game that sucked me into the game for 2 weeks.
On the other side, I never liked MMOs. Guild Wars didn't please me aswell, that's why I already had some fear that the elder scrolls would lose something precious going online and becoming more like a MMO. Anyway, I broke a rule as beta tester (my opinion), but it doesn't matter anymore, everyone that signs up can join it in the weekends. They need as many people as possible to test their systems.
