I just found a new ereader from Pandigital on the FCC website today, and it's not one I've seen before. This one is based on a6" screen, and it has Wifi, a touchscreen, internal microSD card slot (1GB), and an external SD card slot.

I don't know what screen it's using or who made it, but my guess is that it isn't a Sipix screen. I looked at the FCC paperwork for the Benq ereader which went through in February, and the internal design is completely different. If this were a related device then at least some details would be similar.
The speaker, back cover, and internal microSD card suggests that this is a Foxconn design (these details are shared with the original Novel). But Foxconn sends gadgets to the FCC on behalf of their partners, so I don't know why this one showed up under Pandigital's name.
But I can say that this ereader should be using a similar firmware. The user manual is also available, and it looks like it will have all the same features.
