would someone mind explaining to me what in game xmb is?

 Access to the PS3 menu from inside the game.

 Cool, about time.

 I give this thread a 9.7. 

cross media bar, you can open the menu when you're playing a game.

Accessing the Cross Media Bar while you are in a game. Like you can do it in the browser and your music on your PS3

Good news, now confirm custom soundtracks and Software Emulation BC please :D

wow
lets party

oh thats pretty sweet

Coming Soon = E3. Shame they have to make it a special event to get what should have been their a year ago.

In game XMB is the ability to access the menu interface without completely leaving the game. In hopes of doing this, it allows for users to use the message feature and the ability to see who is on (vs watching the screen for the pop ups of people of getting on and off PSN.)

Honestly, I would trade in game XMB for unifed voice chat but I guess this will have to do. Some of the best game that I thought would be great fun felt like crap without voice chat (UT3 and Hot Shot Golf)

jeez, why don't they just include 2.36 with 2.40, and save themselves the hassle. stupid idiots.

Even unified voice chat wouldn't completely solve the problem.

Sony really screwed up by not putting a mic in the box like Microsoft did.
