I preordered in February and played every beta that preordering gave me access to. Yet, I doubt I'll get to play tomorrow.
Weeeell, basically, you are at least a preorderer, which means that you will play it midday tomorrow. I do think you count as a beta tester though, as this is an open beta forum, and thus it would be misleading to announce that the other betatesters would get it early... And basically, these people have already betatested the version coming out, so no reason really to announce it.
