If you’re talking about the Clip Zip model, a new firmware update (01.01.20) was just released late last week. The way I hear it, this will be the last one for this model so you don’t have to worry about missing (or not knowing when) any fw updates are availble in the future.
As far as the other current models (Clip+, Fuze+) go, they too have reached the end of their life cycles so there won’t be any further updates for them either. The development team is most likely working on SanDisk’s next model release that normally hits the market in August.
