Guild Wars 2

Have anyone found out what that was yet? i cant find anything on the web.
Its an hidden area and it seems like a puzzle but i just cant figure out what to do.

For those who are interested in checking it out its after the last boss of AC exp hodgins path. Theres some kind of stair in ruin that you can climb, then theres an hidden entry on top of it. Then theres some pillar connected to each other with invisible ramp. fun stuff

You sure this isnt just a tease by anet?
