Kind of like the GF2, it's not a huge upgrade over what's out there now. There are only marginal improvements. With the same sensor, I doubt noise performance will be markedly better.
The earlier rumor that this February release would include an Olympus pancake is a bit more interesting. I wonder if they have a revision of the 17mm or if their wide angle pancake is coming.
The Penpal seems like a fun little accessory (with limited market appeal of course), although I wonder how my phone will like working with 15MB RAW files before uploading to flickr?!? Maybe RAW+JPG shooting will be required...
