Looks like Sony is preparing to freshen up the top end of its laptop range with a pair of new VAIO series, the SA and SB. An Intel Core i7-2620M is found populating a listing for an SA1X9E/XI model, alongside 4GB of DDR3 RAM, 128GB of SSD storage, AMD Radeon HD 6630M graphics, and a 1600 x 900 resolution squeezed into a 13.3-inch screen. All that for a measly £1,571 (nearly $2,500). What's intriguing about that 2.7GHz dual-core CPU is that Intel lists a February 20th launch date for it, potentially giving us a hint as to when Sony will put the trigger with its refresh. The VAIO SB laptops are set to be the tamer offering, being built around the latest Core i5 chips, though we've yet to know for certain what any of these new machines will actually look like. So, for your speculative pleasure, we've embedded a video after the break with some prototypes spotted at CES that could end up slapped with the SA / SB labels.
