Sony is to release a sported focused flash based MP3 player later in the year with a built in pedometer.

The new player, which looks like a pen, will come in two variations, the silver-coloured 1GB NW-S203F and the black-coloured 2GB NW-S205F.

In addition to the pedometer, the players are rumoured to feature a calorie counter, stopwatch and be water resistant. An FM tuner and a 1-Line OLED display are also present.

As with other players from Sony, the company is promising a lighting fast charge time of just 3 minutes for 3 hours of play and a total playback of 18 hours on a full charge.

Both listed for pre-order at Amazon for $119 and $149 respectively, since the discovery however has removed them from its listings presumably because we weren't supposed to know about them yet.

Expect an official announcement later in the year.
