Apparently, according to some rumors suggest, Sony Ericsson would be preparing a terminal with dual-core processor.
Although nothing is confirmed yet, it seems the model will be called Xperia Duo and will carry a 4.5-inch screen size, 8-megapixel digital camera with Exmor R Mobile and ability to record Full HD. The dual-core processor will be Qualcomm and although no one knows for sure, will be 1 or 1.2 GHz
For now, they are all rumors, so you have to wait for official confirmation.
