I'm pretty sure, once Home is available to everyone, that yeah there will be more things to do, and of course more people around...
I also agree that Sony will have to step up their game. Especially now that you've described it as getting kind of boring.. Surely they'll answer the calls and improve and add tons of new stuff..

As for what i'm looking forward to in Home.. Well the whole idea of Home really excites me.
Just creating your own apartment and avatar, is so cool and being able to meet up and do a whole host of things with friends, and going straight into games.. It brings a whole new concept to online gaming and the social side of gaming itself...
