Sony plans to launch PlayStation 3 firmware 2.7 "in April", according to a pair of developers speaking to Eurogamer anonymously.
Speculation about new firmware intensified overnight after vg247 reported it was imminent, and Insomniac's James Stevenson implied that it would be required for a new Resistance 2 patch to work.
The Resistance 2 update - version 1.5 - had been announced for Thursday, 26th March in a GameSpot video subsequently pulled, and includes the option for two people to sign in with separate PSN IDs on one system for co-op - a first for the PS3 and something the current system software presumably can't handle.
The patch also reintroduces the Meltdown multiplayer mode from Resistance: Fall of Man and a new "Superhuman" difficulty level for co-op.
The GameSpot report said that it would be joined tomorrow by a USD 5.99 premium Aftermath map pack (details TBC, although maps are said to be smaller-scale), and new downloadable skins for USD 0.99 each.
On the firmware, Stevenson had written on a Joystiq thread, "Resistance 2 is the first game to fully log-in two PSN accounts... And it was dependent on a Sony update, hence why it wasn't in when the game shipped."
Sony couldn't confirm the release date or any other details about the 2.7 firmware at the time of writing.
