Currently on Anime and Manga.SE when a question asks "when is Series X coming out?" or "will there be a Season # of X" i do a quick google search, if i find nothing creditable in the first 10 or so results, i VTC (Vote to Close) as off-topic using the prefab off-topic reason about unannounced future events.
Arqade as a similar off-topic prefab close reason
Questions about unreleased or illegal content are off topic on Arqade. We only support questions about games available to the general public through legitimate means.
i came across this question asking about when the rest of the story mode in pokemon duel will be released.
now ignoring that it could be closed for the website request since that's off-topic, if i was to go to vote to close this as off-topic because it's a question about unreleased content of a game, should i do some research to see if i can verify that there isn't a official statement indicating an answer to this?
while the subject is the above question i am asking on a more general basis given that with Online Distribution you have DLC, Mobile and Early Access games you're bound to see more "when will feature X be added/released" for games that have been released in a certain capacity but add on more content (ie. Pokemon Go - when will gen # pokemon be avalible?)
