[quote name='The Mana Knight']And there's a pretty good reason why PS3 can't currently do it:

It all has to do with RAM issues. The XMB eats up too much RAM currently to efficiently do it. Right now, it's up to the developers to implement it. It's like trying to fit a large elephant into a tiny box. If there's not enough RAM currently to access the XMB to do stuff, then it can't be done. It has nothing to do with PS3 being out a year. That's all there is to it and that's why I want everyone to shut up about it (it's been mentioned over and over again, which is why Eric Lempel once said he understands people want this and it's being worked on "please understand that we hear this request and are working toward a solution. When I have some more info to share on this, know that I will do so here on this blog.", which means they are still trying to reduce the RAM the XMB uses up to hopefully implement it one day). The 360 doesn't have this problem because it has 512MB main memory, MS is a software company afterall, and their design is far from eating much memory up. Unfortunately, Sony can't just kill off PS3 and start all over again, with a console containing more RAM in order to do this stuff.
Cross game invite will never directly happen, since PS3 was never designed to do that in the first place (many games use a different invite system and that would conflict). If certain games now don't have invites (like Warhawk, Full Auto 2, etc.), then there's no way they can have invites in the future regardless (Future games might be able to). Accessing messages is a different story because they can be done (but not until there's sufficient memory).
By the way things seem, in-game messaging won't be a top priority, after looking at the recent G.A.P. poll:
-In-game access to PSN messaging
45% (620 votes)
-Ability to play my own music from the XMB while in-game
51% (710 votes)
-Larger buddy list and buddy-list features such as categorizing
4% (58 votes)[/QUOTE]
I honestly want to strangle you more and more each day.

What's this? A Pre-launch PS3 video with in-game XMB? Say it isn't so!
Edit: And before you reply claiming that the video shows a XMB with less functionality, I'd like to point out that a limited XMB is all we want. No one needs to pull up a movie in the middle of the game, we want basic features like a universal friends list and access to our music. I don't care what some bullshit poll by a bunch of Sony nuts says, there are tons of people who want this. Sony has the ability to do so and they haven't done it yet.
