When will they choose the beta testers?

One Week..

Tomorrow the day after that and the next day after that. If you dont get a email about it then you're not in the beta.

Yep basically what's said above. Around E3 I expect. This needs closing as the question has been answered. Wish people would look at some of the other threads about the beta rather than ccreating new threads that clog up general discussion.

for the entire week of e3
