I wonder if that new manga with Rockruff is going to lead into anything significant.
There is one reason to be shocked by this series. The author is no other than Tenya Yabuno, creator of Digimon Adventure V-Tamer 01! This is essentially the Digimon equivalent of Pokémon Special. I have high hopes for it.
It is also worth noting that serialization is on Monthly CoroCoro Comic, rather than the Special or Ichiban spin-offs. That can mean two things: it's either going to be a 5-issue series, like XY: Ryū-ō Legend and HGSS: Jō's Great Adventure, or it's going to be a relatively long one, like DP Adventure. Certainly interesting that it launches three months before the games. Those comics typically only get one chapter before release.
