Back to waiting I'd suppose....
Tho I could pose a tinfoil hat conspiracy THEORY to you all...
This leak about a potential (now refuted) July release was a PR maneuver/ market survey started by Samsung to see if they could market a 3g GSII, or actually had to slightly redesign it for a 4g LTE version.
My reasoning:
1.Samsung wants to build hype for their phone and tablets and pull attention off of Motorola/Bionic (since the Tab is guaranteed, and Moto/Xoom/Bionic all had major news this week. This leak brought all the attention back to the GSII tab and phone, especially since it would have meant undercutting the Xoom's 4g, and undercutting the Bionic entirely )
2. Samsung wanted to test waters to see if a 3g Gs2 would fly, or whether it had to have 4g via public response (Response was overwhelmingly in favor of 4g, especially given the phones impressive stats, and that it's main competitor would be the Bionic )
3. A 3g GS2 would require little extra dev time compared to potentially squeezing a 4g modem in/potentially making the case thicker, and could have made the proposed July date with little modification (Pure speculation on my part, I have no idea what, if any hardware changes really would have needed to be made for a VZW 3g GS2)
