July's only Shueisha colour release was a single Dragonball Super. August seems like it's just going to be the next one. Dragonball's colour release is going to end up closer to its black and white release than One Piece (but still 6 volumes behind, so based on other releases they might still do another couple before giving it a break).
But hey, September is looking to be a big One Piece month anyway, with volume 97, Colour Walk 9, Magazine 10 and the box sets, so maybe they'll give us one more nice thing to go with it. Or they might want to avoid oversaturating the release window any further and hold them back another month or so. Coming out alongside the digital black and white 97 wouldn't be too bad either. I just wish there was some concrete information about what to expect.
