Well, this is Kishi expanding the Narutoverse. And his name is really Bolt. It's just that the Japanese have a strange way of pronouncing things. But, we won't know what he's like until later.
True, I just feel personally the Narutoverse doesn't need expansion. For me, it all begins and ends with the dream of a young blonde haired ninja. He fought for his beliefs, he grew, made comrades, changed the world (kinda). The Curse of Hatred was snuffed out, the big bads from primordial past defeated, and he ended up with a woman who has always loved him. (But then again, this is all coming from a guy who thinks DBZ should have ended with Frieza or Cell)
I understand how it is a reference to his cousin Neji, but there was nothing else to call him without the spelling of "ruto" at the end? I doubt the Japanese language lacks synonyms for words. To me, it seems like shameless fame leaching (like how the last GT movie was about Goku Jr, not actually Goku). I guess I expected different since Kishimoto made Minato and Naruto very distinct people.
