It's hard to tell from the answer but this Michael Dahan response from the TFOT interview may not bode well for the much anticipated firmware upgrade:
Q: The current firmware has some bugs and is missing a number of important features, including folder and subfolder support. When should we expect the next firmware version, and what fixes and improvements will you integrate into it?
A: The next firmware will be ready March 31st and will integrate mainly bug fixes. Our main priorities are, of course, folder and subfolder support and more generally the container support (ZIP, etc.). We will stabilize the PDF reader and enhance and accelerate the user interface with a better button events handling. The global idea is to support as many formats as possible with maybe an ePub support in the near future.
