Here is something for you guys to think about, that this isn't only for PS3. Remember Sony are wanting to move the PSN to a bigger audience. Some of those option may include the Sony Bravia line. They are intergrading Netflix into their TV, also 3D is coming, if you look at the full list there is something that says about Sony exclusive on brands.
Also the PSP could be one of those options as well. The trophy alerts could mean something different to them. Maybe it could alert us when a friend get's a trophy, although i don't know if i really want to know that, but it could mean that. The music services may be for the TV's and still be free the ones in the EU, because US doesn't have iplayer or vidzone.
So if i were you guys i would think bigger than only the PS3.
