Guild Wars 2

i finished the “50 WvWvW invaders killed” and the “5 dungeons done”, but the monthly acheivement bar says “7 of 9 completed” and progress is 77%… are the rest needed acheivemnets going to be introduced later in month? (probably in new event?) …. or am i missing something else?

.. many thx in advance for your answers

There is a content patch on the 15th this month, and the monthly achievement seems as if it will require things from that.
