Other articles abound (now that I looked, LOL).

It looks like WiFi and touchscreen are the big differentiators. I'm guessing that we will see other changes that will apply to both readers.
One advantage could be OTA updates. I am not sure that I would see this alone as a good enough reason to purchase a new reader. If the new one also had a dictionary, I might. The touchscreen could make that kind of thing possible. Certainly for folks who sometimes read on other devices, the ability to sync them all up OTA would be a good thing.
Mostly though I am glad to see that they are going full steam ahead with eInk. So may non-eInk devices with Kobo store and apps are out there now.
It's interesting that the company making the hardware was rumoured to be out of business, not all that long ago. I wonder what the backstory to that is.
