The name change does cast doubts for me. Its part of a cycle in some sense: before Sega's last system, the Dreamcast, had a weird name with symbolic meaning too, after all. That's not to say the names that should be good all belong to successful systems: Jaguar, anyone?
But in some ways, its like an eccentric genius who is all "my new invention will revolutionize the world!" Well, he starts doing things that are eccentric, but that's how he's always been, so you write it off. Then things get very different, but again, genius is often misunderstood. Now he start's wearing a tutu. >.>
