Potentially true but at least B&N has fallen in line with their PubIt! platform for indie authors on the Nook. Exact same pricing structure to revenue sharing %s. And last I knew B&N is the only thing even CLOSE to competition for the Kindle store right now, and even it is way behind.
iBooks isn't even a blip last I heard. After all you can just read kindle and nook books on your iPad. Selection is crap too so most people I've ever asked don't even look these days it seems like.
