It's based on Wowhead's data mining from beta. The chant is +1 stats to cloak, and has the same chant level requirement as resistances. Yes, it's a guess, but it seems pretty likely.
As for the other resist gear, Wowhead has no information on that the last time I looked. We will just have to wait and see. Nothing in beta is confirmed as going live, and anything that does go live is subject to change.
