I seem to recall a Raiga movie being announced last year.

The thing is, before that, the next thing with Ryuga was only announced as a movie, and it ended up being a full second season with Ryuga and Rian. Wouldn't be shocked if the same ends up happening with Raiga.

I think we're due for the now-annual event where they announce a shitload of new Garo stuff. We might get an announcement of sorts then.

A quick google as far as the last couple of years indicates late-November. Also, amusingly, a lot of people who were watching the anime last year and not even really knowing Garo's tokusatsu roots, a little shocked that so much stuff was announced all at once last year.
