If we act now, they will have a chance to edit the Series 5 finale so there is still more story to tell. They might 'officially' tell us after Series 5 airs, and by that time it will be too late. And Merlin will be done and dusted... forever! Even if there is a Series 6, we ultimately have nothing to lose in the long run as oppose to waiting for the 'official' announcement.
