Any hacks in development yet?
I just wanted to know since they're online again

The fact that it is almost impossible to log in might be a problem though. I wish they had more open servers >.<
They'll probably launch with a couple more servers and channels to each server. This is open beta and open beta for a lot of games is this crowded, if not more. Not all games, but quite a few of them. Also, this has been an anticipated game for like, what, 10 years now? So it will have quite the lot of traffic. But yeah, I wouldn't expect much hack development until people can login with ease.
