Exclusive Beta - Open Beta....me confused

[Rayzer]

Ok. So I finally check my email and low and behold I got in the exclusive beta. But the thing also says that the NDA is being lifted and something about the open beta and CDs.

Now I am halfway through a 200 something meg download that I'll probably finish off tonight.

Anyway, my point is this.

I haven't really been following PS much and I don't know where things are at. Is there a point to being in the exclusive beta? Is it different than the now open beta? Is there a while still before release or am I getting in the beta 2 weeks before it hits stores.

Anyway, trying to figure out if I actually got something meaningful and if I should bother playing the beta or just wait till release.

Thanks.
