Sony may need to address a larger issue: How does PS3 and PSP fit into the Internet ?
If they are serious about Internet integration, I think they will have to port a modern browser core to the Playstations. Sony may make PSN-specific policy decisions, but technically they need to be on par with the mainstream.
On the casual gaming front, the world is running away/ahead with web games. SOE is not as visible as it should. To the casuals, the Playstation family is not known to run simple games already on their favorite devices (like AngryBird on iPad/iPhone). Very few Playstation IPs are known to the casuals (e.g., LittleBigPlanet, Ratchet & Clank). The Flash/iPad/phone games are free or low cost too.
On the app front, PS3 is still rather limited. The recent Photo Gallery and Video Editor apps managed to keep PS3 up-to-date (Photo and video upload are 2 of the top surveyed use cases for Internet communities worldwide). It is a welcomed update, but they are not setting any trend here.
I hope the PS3 and PSP(2) become more open (read/write to SMB drives, RemotePlay/Desktop for PCs & Macs, platform neutral video rental, etc.). Some of their IPs should leak to Internet communities in a meaningful way. The Facebook spamming mechanism cannot be relied on.
The PSN+ packaging is a mixed bag. While it fails to articulate values to many consumers, there is some forward thinking network business model there. Unfortunately, (as usual), it's only partially done. Unless they focus and get their act together, they may continue to lag behind user expectation. It's the same old piece-meal approach. Simply giving us a WebKit browser doesn't really move the game forward (It's a great start though).
EDIT: The Google TV move is interesting but again, Sony prices the TV too high. >_<
Someone else will take the initiative and popularize it. I haven't heard any major talk after the initial launch. Should bring the functionality to PS3 instead.
