Does anyone know if there will be a trial-option, like Wow's 10 or 20-day trial period?

Thanks

there will probably be one eventually.

IT will just be when the initial rush on the server will have died down and when/or subscriptions starts dropping.

You can probably pay to queue up for the pre-order of the digital deluxe trial edition if you're in Europe.

You'll probably have to wait a year.

Most MMO's don't release trials until some time after the game has come out.
