@corevi: Persona 5 will be featured during this stream, obviously. Not all of the question marks will be Persona 5, but other reveals (Persona 4: Dancing All Night will also be part of the stream). The last slot for February 5th, 21:00 JST probably is going to be Persona 5; the question marks for that slot are the only ones in red on the Niconico live stream page.
The last stream was absolutely terrible, with a Teddie cosplayer getting groped by the VA of Kanji. It will be 30 hours of nothing and at the very end the very same trailer for Persona 5 you've already seen. So don't get your hopes up.
That's wrong for a plethora of reasons. The main one being that that stream was an anime focused, region locked one which ended up announcing Persona 4 The Golden Animation. This is analogous to the November 24th, 2013 stream, not Persona Stalker Club or the Datsu Nugu stream.
- 8:05 PM EST (February 4): The locks previously enveloping the circular icon on the Persona Super Live 2015 website have been removed to reveal a link to the official News Flash! Persona Channel 2015 blog post.
The "News Flash! Persona Channel 2015" live stream will start on February 4th at 1:00 PM JST (which is February 3rd at 11:00 PM EST), and will last for 30 consecutive hours, showing both old and new stuff about Persona. Notably, the event is happening a day before the Persona Super Live 2015 concert.
Persona 5 and Persona 4: Dancing All Night will most likely be shown here, finally.
