Accessories, yes. But much more limited. Things like BT headphones or charger stands specifically for Apple Watch. I'm not sure we've seen the other end of Apple's charging cord. The nifty mag-safe type connector, yes, but I'm assuming the other end is USB. Meaning Apple Watch shows up in iTunes for configuration? It can't be that Apple Watch is solely configurable via iPhone - but we haven't actually been told how this will work.
