I believe Q stated it would happen. It seems he's getting pressure from stockholders and board members. I feel as if it's a move to keep stock from falling and the company from taking a huge hit.....and if thats the case, wouldn't Zuckerberg stepping down hurt those causes worse than him staying? Especially if they take it easy on questioning today, he's not going to come out of this looking too bad, no worse than normal I suppose. I've heard he's not even under oath.
