Chances that my Q9550 is the EO stepping?

I'm really excited over my new build that is finally shipping after a week's delay. I got a Q9550 at DirectCanada. And I heard the new EO stepping (SLB8V) came out on August 22nd. So what do you think the chances are that I got the new one?

Fire up CPU-Z and it'll tell you what stepping you have. The E0 stepping will (should?) overclock higher with less voltage.
