This is great news. The track number thing really bugged me. I'm very happy with this change.
Now, if only they fixed the FM thing -- it always starts out at 87.5 MHz whenever you go to the radio. I don't really need a few seconds of static in my ears.
I'm looking forward to trying out the new firmware tonight. (First step -- remove the track number from the track name and I put there as a workaround).
This must be new, but it certainly addresses most complaints about the Sansa:

Firmware features:
1. Sort by track number
When you choose "Play Music-->Album" and select album name, tracks are sorted by track number rather than alphabetical order.
Same is true when choose "Play Music-->Artist" and select album name.
2.Favorites list support
You can create favorites list, which is a playlist customer can create without using PC.
3. Default language selection
When customers power on the unit for the first time, language selection menu appears.
Gotta luv Sandisk..They listen!!
