Looks like a PS3 firmware update is happening today or tomorrow, folks. We reported details on the upcoming Resistance 2 patch which includes a number of features, one being multiple PSN log-ins. Many of our readers correctly chimed in, saying this is a feature not possible with the current PS3 firmware.
We got confirmation of a pending PS3 firmware update through our comments section. Insomniac Games' James Stevenson responded to our post clarifying the situation. "Resistance 2 is the first game to fully log-in two PSN accounts. LBP only logs you in locally, and does not register both accounts as online through PSN. This is a big difference, and what is required for split-screen online co-op with other folks."
Here's the smoking gun: "And it was dependent on a Sony update, hence why it wasn't in when the game shipped." If the R2 patch is available on March 26th, then a new PS3 firmware update will be necessary today or tomorrow. Obviously it will allow for multiple PSN sign-ins, but will it feature any other improvements? Stay tuned.
