Again GSMArena, "Display has poor viewing angles" is NOT a disadvantage. This gives you better privacy.
IMO the Sony displays used have more natural colour reproduction than the over-staturated Samsung SuperAMOLEDs.
the 701 should be mentioned here. No 1.4 ghz cpu maybe, but an awesome gpu with 128mb dedicated graphics memory, so no need for that. And it offers a lot more features than most of the phones you've mentioned, nfc, fm transmitter, the brightest display, 8gb internal memory, penta band hsdpa, and real usb on the go (without the 19th century live dock).
Atleast this time they should have added front camera ...Expecting Xperia play2 with dual core processor so that i can play gta 3.Also bring Xperia arc 2 with dual core processor & dual camera.
