I think Sony gets the prize for using just about every letter in the alphabet. I dare anyone to rattle off all the phones they have released in the past two years. My family tree is less complicated than Sony’s chart of phones. It looks like Sony has no intentions of slowing down because word is they plan on adding Xperia SP and the Xperia L to the mix.
The Xperia SP will feature a transparent bar so it will be in the NXT series, and since there is an “S” in the name, it will be similar to the Xperia S. It will feature a 720p display, a 1.7GHz dual-core Snapdragon S4 Pro, and Adreno 320 grahics. The codename is Huashan and the model is C530X (C5302, C5303, C5306).
The Xperia L is going to be a lower-end phone. It will feature a FWVGA (854 x 480) display, a 1GHz dual-core Snapdragon processor, and Adreno 305 graphics. No word on the codename, but the model is C210X (C2104 and C2105).
