The second season for Attack on Titan isn't due until sometime in 2016, that's why we got a weird hold-me-over Attack on Titan: Junior High anime. With the end of 2015 approaching, it's no surprise that a preview of the highly anticipated second season has leaked online.
It's unofficial and glorious — to be specific it's a recording of the official preview, with the grainy and distant quality that you would expect from a leak.
Rest assured, there are no spoilers in the preview for the first season. If you have read past the first season in the manga, this preview won't be too much of a spoiler, but if you haven't you might want to proceed with caution.
The second season has been rumored to be ripe with death, titans and more. I cannot wait for this!
