Just a lurker here, but I just happen to be a student at this school and I attended this conference yesterday. Quite surprised to see a thread about it on GAF !
School's name is Grenoble INP Ensimag, one of, if not the, best schools in applied maths and computer science in France (
wiki).
Every tuesday, students can attend 2 or 3 conferences organized by various companies. Here is the list from last year (
here), dunno why it hasn't been updated yet, but you can see Ubisoft also came here last December, should be a solid proof (btw these are not the same presenters, and I'm not going to reveal their names publicly).
Anyway, I can confirm everything said on Reddit was said during the conference, it was interesting to learn more on game development, and I was most surprised to learn that Ubisoft has to wait for Sony & Microsoft review and how they can change things before they release the game.
Edit : btw, i'm not the one who took the pic.
