Ok after a few mins after releasing this anonucement 402 has took it all down and replaced it with this awesome news:
I know there has been an uproar regarding the fact that the Public Beta may be restricted only to US residents. I wanted to give you guys an update and let you know that this is currently an unconfirmed statement, as details on Beta limitations are still in the works.
I will update you PERSONALLY when we have an official confirmation on Beta Limitations so bare with me while I get this all sorted out for you guys.
More info coming soon.
