Sony Xperia GX
The Sony Xperia GX was announced for the Japanese market along with the Xperia SX. It has a whopping 13 MP camera with an Exymor R sensor, a 4.6-inch HD display, Android 4.0 and a 1.5 GHz dual-core processor.
It looks much like the Xperia Arc, but carries a good punch in specs. If you are interested, you might want to wait until the summer, which is when this bad boy is expected for release.
