Well all is based on the curve on xperia gx.
Japan version still a bit slightly different for international model.

T and TX i prefer TX thinner and lighter, battery not big issue for me, since it's 28nm s4 better power management.

I still curious on the speaker model they use and how fast is charge.

Current S3 charge very fast

But overall all still look similar

nope . msm8260 A is dual krait .

Update: Sony Mobile has now updated the white paper which seems to suggest it will come with a S4 Snapdragon MSM8260A chipset (the same as the Xperia T). The product page is still referring to it with S3 Snapdragon MSM8260 chipset though. Hopefully ,the latter is a mistake though.

do you ever read the whole thing but not only keyword ?
no i guess

its funny that how you attempt to use my source as your backup but you don even bother to read it .

Can anyone tell me how is this model different from xperia acro s? The spec look like the same to me..
