If I'm not mistaken, call centers by Sprint are run by Alorica.
People in those call centers are designed to "always tell the customer what they want to hear."
From my experience working in one (I didn't last long, I always told the customer the truth,) they will tell lies, just so you keep your plan/contract/buying their items.
If the S2 does come, cool! But I'm happy with my Evo 3D.
