I have no idea what the anon is talking about, but by now it's been officially confirmed that the anime will continue in aprit, but no mention was made as to how many episodes there will be. And considering that the manga is still on-going it'd say it'd be impossible to make such an estimate yet, even for the producers themselves at the moment.
