A qoute from the playstation blog:
"Also, I noticed a lot of your comments were directly related to accessing XMB features in-game. We understand this is something you want and we are working on it. For the sake of keeping all the comments below on topic, 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."
The actual blog entry seems to be inaccessible at the moment.
