It seems like a possibility that no cover flow in iTunes 11 is the first sign of phasing it out completely. When was the last time you used it on your iPhone? I used to be really anal about having all the artwork, but when you're like me with a massive music library then it just gets a bit tiresome. It's already never been added to the iPad music app and I wouldn't be surprised if they removed it from the iPhone and iPod touch music app as well as OS X (still on Lion, not sure if it's still in Mountain Lion). Though I don't know if too many would notice (in a positive way) if they got rid of it due to it not really taking up any power or resources.
EDIT: iOS, Mountain Lion, iPhone, iPad, iPod touch, etc - I wasn't too sure where to put this thread, haha.
