The fact that his release command is "drink" / "swallow", is leaving me the impression that he just absorbed all the power in that meteor. I mean having a Zanpakutou that endlessly drinks power seems like the most special kind of ability Kubo could fittingly give to Kenpachi. Hopefully we'll find out what it means in the next chapter...or two.
