Yeah, it's not a single, it's a half season "box". Viz just uses single cases now because they're cheap. The market did move away from singles, but they were replaced by 12-14 episode releases, not complete season sets. Complete season sets on the first round are still quite unusual.

And there's nothing wrong with not buying it and waiting for a complete collection (I might do that myself as long as it's on Toonami), but you shouldn't expect them to release a complete set just because you'd prefer it that way.
