Square Enix Presents isn't an event. It's S-E's irregular ad-hoc Youtube streams. Kinda like Nintendo Directs, but each program is usually for a single game. They're promoting Bravely Second and Final Fantasy Explorers this way too. So it's not a specific event to look forward to, they just mean that in future they'll probably have updates using this platform. There's currently nothing announced on the Square Enix Presents blog: http://www.jp.square-enix.com/sep_japan/
I see, I know what they are, I just wasn't sure if they were regular or not.
