Please use the official thread for all discussion related to the Evolution of Combat, and the current BETA.
Also, it has already been confirmed on the RuneScape forums (Combat BETA section in the sticky) that the BETA is going live at some point no matter what. Jagex appears to be lenient with the length of time the BETA is live, stating that they are willing to extend the BETA for a couple of extra months if need be, until it is tweaked to perfection and is widely received positively by the players. I find this slightly comforting and I hope they mean it.
