Normally I would file this under the rumor bin, but there's a thread at NeoGaf where an EA employee confirmed it and a moderator posted it originally. NeoGAF thread.
Source.We've finally received word that the long awaited, and much rumored, PlayStation 3 Firmware Update 2.40 is indeed the real deal and is said to be coming relatively soon. Many of the most requested features, such as a universal friends list and in-game messaging will be included, in addition to a few rather nice surprises (*cough*soundtracks*cough *). We definitely can't divulge all of the details, but trust us, it's coming.
We aren't yet 100% sure of the actual release date, but all signs point to sometime in June. We're guesing that Sony will probably detail 2.40 in the coming weeks.

Makes sense as well, since MGS4 is coming.
