First thing is that PS3 games will now be allowing you to access arcade games within home for free. Resident Evil 5's space in Home will have an arcade game that is accessible for free if you own RE 5.
Second thing is that trophies you unlock in PS3 games will allow you to get items within home for free. Yes, trophies will be worth something for more than gamerscore.
I don't know how far they will take these developments, but if they have a lot of multiplatforms do this, it may have people buying PS3 versions instead of 360. Then add in that they may be packing games with Bluray films together in the future too. The war between 360 and PS3 should get a lot more interesting soon. MS must have some developments in the works as well. http://www.n4g.com/gaming/News-291131.aspx
