From Fender's website,

The American Professional II Stratocaster draws from more than sixty years of innovation, inspiration and evolution to meet the demands of today's working player.

Our popular Deep "C" neck now sports smooth rolled fingerboard edges, a "Super-Natural" satin finish and a newly sculpted neck heel for a supremely comfortable feel and easy access to the upper register. New V-Mod II Stratocaster single-coil pickups are more articulate than ever while retaining bell-like chime and warmth. An upgraded 2-point tremolo with a cold-rolled steel block increases sustain, clarity and high-end sparkle.

The American Pro II Stratocaster delivers instant familiarity and sonic versatility you'll feel and hear right away, with broad ranging improvements that add up to nothing less than a new standard for professional instruments.

These stellar instruments are now being offered in a Limited Edition thinline configuration, with semi-hollow ash bodies and four beautiful transparent finish options. These wont last long!
