Well I would wait and see if everyone takes to that game like duck to water or not. I am betting we will but have to see. tho I may order my copy SOONEr then expected aneway lol.
I think JO is dead for us, regardless of whether we give ArmA it's own forum. However, I think it easier to just rename the OFP forum to cover both, as OFP itself will likely get little traffic itself anymore.
