In an attempt to gather what we know:
Dates
- Date the Persona 5 and Persona teaser website domains were registered were on June 25, 2013.
- Date of Persona 3 The Movie #1 release: November 23, 2013 (Saturday). Released in all 6 prefectures and capitals featured on the teaser website.
- Date of reveal: November 24, 2013 (Sunday) at 20:00.
Website Information
- The persona5.jp domain and p-ch.jp were both registered on the same day, June 25, 2013, by Index corp.
MysticDistance believes that the former domain was registered so that it might eventually redirect to the latter.
- The reveal will be game related as the P-Studio logo is displayed alongside the Atlus logo. Most likely Persona related considering the development studio and the domain name.
- There are specifically three boxes at the top of the page.
- The red coloring of the website, as toddhunter and others have pointed out, resembles the red coloring of P4A2's character select screen:
- The only interactive element of the website are the three boxes and the six locations at the bottom of the page. When a box is clicked on, it shakes for around a second. When a location is clicked on, it shakes for around two seconds. When any of the items is clicked on and another is clicked while the first is shaking, the first item will continue shaking indefinitely until it is clicked once again.
Previous Teasers
The only Atlus teasers of substance in this style of a mysterious website or ad I've found are:
-
Shin Megami Tensei: Devil Summoner 2: Raidou Kuzunoha vs. King Abaddon via the "On the day when Yin and Yang come together a new jiken (event/incident) will begin" tease in Famitsu on a July 2008 issue of Famitsu. The game was announced the same month.
-
Devil Survivor via a Famitsu tease in an October 2008 issue. Doesn't
really count since the title was outright announced, but it was still a teaser.
-
Shin Megami Tensei IV via a May 2012 two-page ad in Famitsu. Doesn't
really count either since what this game was as well as its platform was pretty explicit and the official website launched a day or several after the tease.
That's all I could find. It doesn't seem that Atlus has ever really teased a video game product via an actual website before? Other than things like a Persona soundtrack announced via an ad in Famitsu or a teaser website for the Persona 3 movie, all of their games seem to have been teased via Famitsu?
If this is a first, based on their history, I really wouldn't think this would be something insignificant like an iOS game or browser based game.
