Frederick Raynal, the creator of a famous franchise known as Alone in the Dark put up a new teaser on ludoid (scroll down to see the teaser).
I do not know what the first message on the chalkboard says, but if you click it you will go to another page, and if you use Google Translator, this page says:
“Message to the attention of the MLA: ‘Sorry, it is not LBA3!'”
But this project we always take to heart and your enthusiasm is precious to us. Thank you. Fred“
LAB3 probably stands for Little Big Adventure 3.
There is also an Ubisoft logo, so it will be published by them, and that’s pretty much all the info right now, i guess all we can do now is wait for E3.
