No it's not sure. If you see #FF14 tag on twitter you will see many JP users are not selected even after SQEX has sent 3 waves of additional invitation.
This is because alpha version is started with single one server, it just can't bear all users who signed up. Dev will add servers before global alpha. But they didn't say they will send invite to all global users at Nov.26. When server is stable enough to run 24/7, they will let more users to get in. So all we can do is wait and pray for our luck.
