A new PlayStation 3 firmware available in April.
Firmware 2.7 has been rumoured for some time, following comments from Insomniac's James Stevenson. A new patch for Resistance 2 is to include features not available in the PS3's current firmware.
"Resistance 2 is the first game to fully log-in two PSN accounts. [LittleBigPlanet] only logs you in locally, and does not register both accounts as online through PSN," said Stevenson in a Joystiq.com thread.
"This is a big difference, and what is required for split-screen online co-op with other folks. And it was dependent on a Sony update, hence why it wasn't in when the game shipped."
The Resistance 2 update was planned for tomorrow, but this is put into doubt with a pair of anonymous developers telling Eurogamer that the required PS3 2.7 firmware update will be available in April.
