"Sorry but I went to GDC for the last 5 years and Blizzard shows off a ton of stuff to full pass holders / investors. MOB was huge part last year and after GDC Beta went live and so it will happen again this year. I can't say what will be shown on the teach side but it's amazing and once they see the reaction that they want and gets great praises like last year. A beta will be revealed, it's all about the aww and wow factor from these events! What will be the forefront of the year to come. If it goes great and wins the side of the game industry then the customers will get a taste of what was shown / played in the beta forum / open beta etc."
I get that looks sketchy (and hard to read), but if he's right, that sounds a lot like a press event.
If someone could tell me what MOB stands for I'd love that.
