We expect the focus of the new iPhone will be iOS 5, a speedier A5 processor and a higher resolution 8 MP camera with a small possibility of a larger 4 inch screen,” Blair wrote. “We believe the casing will be largely similar to the iPhone with some particular modifications to the antennae [sic]. We don’t expect a second, dramatically different iPhone to accompany this as we don’t think Apple needs to have 3 models in the market to address the high end, mid-tier and low end since the iPhone 4 (with memory lowered to 8 GB) will drop to $99 and effectively attack those markets.

Occam’s Razor and all that.

Also, if true, it would just go to show how insanely inaccurate a rumor can be and still have legs.
