sdr: You are incorrect. Apple reports that the new iPod still supports MP3, VBR and WAV. It never supported WMA and has done very well in spite of that fact.
High fidelity Designed to give you the best portable digital music experience ever, the iPod delivers the highest sound quality from input to output. iPod supports the most popular audio formats — including MP3 (up to 320 kbps), MP3 Variable Bit Rate (VBR) and WAV — giving you access to a wide range of audio file types. And iPod is the only portable digital music player that supports the AAC format (Mac-only), which features CD-quality audio in smaller file sizes than MP3, so that even more songs fit on your iPod.
