I think it will be called the iLoop.
Apple’s address is 1 Infinite Loop.
To call it an “iWatch” is stupid. They never called their music player an “iJukebox” or “iMusic” or “iPlayer.” Calling it an “iPod” left it wide open to do more than play music — as it eventually did; offering, for example, video and photos. And “pod” was a brilliant choice, since the iPod was white — and most people connected it to the white pods of the movie 2001.
