According to EB Games, (in Canada) the Resistance 2 public beta codes need to be resent because the codes they received we're already expired upon arrival. I got this bit of information directly from a EB Games employee.

Quote EB Games employee: "The Resistance 2 beta codes we're sent to us, but when they arrived they we're expired, so there was no point in calling [or emailing] our customers."
