I was searching in the playstation blog and i found this.
according to a NIS employee firmware 6.0 should be out on the 10thHi Killzone_Kid! This is what has been decided for the Badman demo:
we’re going to re-release it next Thursday, 10 Sept,
by which time Firmware 6.0 should have been released.
Sorry for the wait!
So to believe in a new CFW ?
