Looked again at the info Koichi posted about the upcoming update and more practice is one of the main features. So by that, I’m guessing more sentences will be made to go with Season 4 onwards.
His long term plan is to eventually stop using Anki and use a built in srs. As for Kanji learning, at the moment there’s Kanji on TextFugu and WaniKani (although still in alpha, it will grow over time). Both should be consolidated into the one. WaniKani looks fantastic so far. Using Anki does get dull at times but is still reliable.
