PS3center.net - Story: [UPDATE] Sony Clarifies Killzone 3 Beta Spots Details

So the number of people with access to the beta has just dropped by half, because there will only be 5,000 places available in each territory, rather than the aforementioned 10,000.

UPDATE: Guerrilla Games Product Manager, Aryeh Loeb, has confirmed in a comment on a SCEE blog post that, "It’s actually 10,000 (beta places) for SCEE and 5,000 for SCEA."
