No, from 4 leakers (2 on NeoGaf that are betting their accounts) that have got a few things right in the past, and are supporting each others claims. The mock-up was made from their list. We haven't seen proof though.
In two weeks the game will be released in Japan and that's when other stuff besides the Dojo will be revealed. I think discussion about the full roster and Subspace Emissary (ending + final bosses) should go in spoiler tags. I know I won't be able to avoid spoiling the full roster but I want to try and avoid any spoiler about the SSE. Discussion about the daily updates shouldn't have to be in spoiler tags, as far as I'm concerned as I will be following them anyway.
My store hasn't sent the game yet and suddenly moved the release date to end January. Sent them a mail about it, maybe haven't got (enough) shipment yet or something like that.
I really like todays update, adds another layer of depth to the Subspace Emmisary and really makes you want to collect those stickers. I'll be very annoyed if the release date is any later than April for us.
