I would say there's definitely room for many sorts of Pokémon Anime, and I'm somewhat glad in the last decade or so TPCi branched out enough to the point these alternate miniseries and shorts have now become a common occurrence rather than a very occasional diversion from the main Anime series.

However, solely going by trends, I kind of doubt if TPCi would ever invest in a long form take on the concept, at most relying on short miniseries. I also believe 'anime' is a pretty important qualifier in this sense: Path to the Peak was clearly written in the style of a western cartoon and did quite well with it, but it also often skimmed over parts of the actual card game to focus on the interesting moment. While I'd love to see a more YGO/Duel Masters/Vanguard-flavored take on the material, I believe the way the TCG is often very passive and low on counters in the opponent's turn would risk to not make a show cinematic enough to allow the counterplays and back-and-forth a Duel Monsters clash would provide.

That said, I'd definitely be interested to see it happen and which form it would take, even if it's somewhat unlikely.
