Looks like the ARR beta invites will be going out soon. Possibly sometime this week. Got a tweet today reminding me to update my email for the codes. It was also recently confirmed that any buddy codes folks had with 1.0 will be useable with ARR when it launches. Also, any unused registration codes for 1.0 can be redeemed for ARR, so if anyone is still in possession of them, hold onto them.
