The Philips PSA612 4GB Sport MP3 Player with FM Tuner is available for pre-order on Amazon.com.

The Philips PSA612 was first announced as PSA610 in February. Back then it was still co-branded with Nike.
The Philips PSA612 features a 4GB hard-drive. It is Microsoft Plays For Sure complaint and supports therefore WMA DRM music files.
The new Philips player will ship October 1st.
The Philips PSA612 sells for $189.99 on Amazon.com. The Philips player has a cool design and the price is all right. A HDD for sports is not ideal, but I assume Philips put enough buffering electronics in there to not get a skipping issue.
To play it save a flash player like the 4GB iPod nano should be considered.
