Hmmm that post was made on the 22nd and said all will be in by tomorrow by 2-3pm. I still havent heard anything so guess they are either lying or they have been delayed for some reason. Seeing as most are in now though am thinking for some reason I've been over looked. Not to bothered as October bring's plenty of gaming goodness and I wont have time for the Beta then anyway.
Edit** According to one of the developers on the EU PS forums the beta invites were sent out between Thursday the 18 and Tuesday the 22nd. Am sure I'd signed up but maybe not. Oh well sounds like alot of hassle anyway going by Matt's post lol.
