Thanks to our Project Manager, Simon, for giving me a better link to the new mp3s:
I have also had a couple of questions regarding the new mp3 format audio books. Here's the popular one:
"If it says WMA, but not MP3, can it still play on the Zen mp3 players we have been using all along?"
Yes -- the WMA files will play on your Zen/Sansa/Coby/etc players that you've been using up to this point. The mp3 files will play on these players as well. The only hitch is that, in order to transfer an audio book directly to an iPod, the audio book must be in the mp3 format. WMA format audio books will not play on an iPod.
