The World of Warcraft fans are happy to see an upgrade button inside their battle.net accounts for World of Warcraft. The button doesn’t lead anywhere special other than the default World of Warcraft page, there is no option to upgrade or pre-order the next expansion at this time.
But, it is nice to see that things are moving and Mists of Pandaria is not far from being released.
Some fans said that the upgrade button is just a bug, the button was there all day, today, there is no way it can be a bug as things don’t appear by themselves on a web interface.
