Hah ! Can't blame you because I have similar thoughts. They probably presented in the conference to cultivate leads. They can already demo web integration using existing deployed services.
The PS Eye opportunities require more R&D (e.g., Recognizing controlling objects by color instead of motion) and longer development time (EyePets slated for 2009 since about a year ago). It's pretty much still a work-in-progress.
Home and LBP took 2+ more years since Phil announced them (Picture Frame coming out in a few week's time). They had to develop the infrastructure, developer tools and content from scratch during this time.
Web integration is already here in various deployed forms (e.g., Xi, MySito, YouTube upload, SingStar web integration, PSN Portable ID, The Last Guy promo game, KZ2 web game, etc ...). FaceBook integration is easy. You only need to output FBML (like XML) using templates. OpenSocial is harder. What's tricky is (i) finalizing business models and focus, and (ii) the communiy backend that supplies the data (i.e., Playstation Home, XMB voice chat, playstation.com, ...), which is just starting.
Sony will need to simplify and package the combined services better. They may be able to deliver in a piecemeal fashion, but integrating into the core PS3 experience will likely take a l-o-n-g time.
