A small Xperia army seems to be assembling in secrecy - clues of yet another droid appeared in NenaMark and AnTuTu benchmark results. It's called the Sony Xperia LT25i 'Tsubasa'.
It's an Android 4.0.4 Ice Cream Sandwich device, powered by a Qualcomm Snapdragon S4 chipset with a dual-core Krait processor at 1.5GHz and Adreno 225 GPU. The screen on the 'Tsubasa' has 720p resolution and the phone will use on-screen Android buttons (the reported resolution of 1196 x 720 gives that away).

The LT25i is the international version of the Sony Xperia Tsubasa and will likely have LTE connectivity. There seem to be a few more versions - LT25h (HSPA+), LT25c (for China), SO-01E and SOL21 (for Japan's NTT DoCoMo and KDDI respectively).
There's a number of Xperia phones yet to be announced, even a tablet, so we can't wait for its pre-IFA press conference to start (Sony will be presenting its stuff on August 29).
