TheSixthAxis: "Want more information on Firmware 2.40? Well, expect an avalanche of information, including the World's first official look at the PS3's Trophy system, at 4PM GMT today (8AM EST / 5AM PST), which is also when we assume the PS Blog will upload their 2nd video."
"In the meantime, a few nuggets slipping out include rumours that not all games will support the in-game XMB when Firmware 2.40 launches - if the game doesn't support the new standard apparently the game will simply show you the default in-game screen (with controller options, etc) instead. Presumably games can be patched, but we'll see."
Edit: 1PM, sorry, not 4PM.
