There is no info to be had, other than the confirmation that there is a beta for PS3, and that there is a Non-Disclosure Agreement for everyone who is a part of it. They will probably stick to EU, where legal prosecution is possible if someone leaks the beta game or something serious like that.
Ah, ok. Well, i got a PM from Gstaff saying:
If we have any news on the possibility of a public beta, we'll let everyone know.
So, no news yet. I'll keep my eyes and ears peeled though, im very hopeful, especially if they make it a public beta
