I think if blizz really wanted us to not have 2h, they could have easily just made us unable to equip 2h weapons. This is not the case.
Secondly alot of you seem to be thinking that the stormstrike restriction means they mean to kill 2h for good, but I don't think this is true either:
To me it seems like more of a balance change so that 2h doesn't actually become stronger than dw, especially in burst situations (pvp) where you now have the possibility, with echo of elements, for some insane 2h burst from an ehancement shaman. I don't know if anyone's tested it yet but I have a suspicion that 2h, even with the complete loss of stormstrike, may be pretty viable as far as not being completely damageless as to be unusable even for fun. Besides, don't forget we have primal strike
