Update: The (short) wait is over.

Sony just announced that PS3 firmware 3.40 will hit Network Update tonight, bringing with it PlayStation Plus support, in addition to social networking enhancements that strengthen integration between PSN services and Facebook.

Other enhancements include the ability to rate purchased content on the PlayStation Store under a five-star scale system and additional power save options. PlayStation Plus, if you haven’t already heard, is a optional premium tier for PSN users. It adds several incentives on top of the base PSN offering, including early access to betas, bonus content, and free access to select PSN Plus sponsored titles. More deets can be found here.

Due out alongside the aforementioned PS3 firmware update is PSP firmware 6.30, which also adds PlayStation Plus compatibility. There’s also a vague mention of “other minor features” thrown into the mix. Looks like we’ll have to wait and see what surprises await.
