I'd like to see a demo disc with like 10-20 Sony exclusive games on it. Comes with the system, or you can just get it free (might help sell software).
Also, like to see some free download game/movie bundles. Buy the system and get $100 in downloadable games/movies or something like that (would cost them next to nothing, would add to the value prop., and would encourage people to buy downloadables too).
Also, disc based versions of Wipeout, Siren, and/or PSN collections would be cool.
Announce more collections of HD ps2 games with early access to betas/demos.
Revamp home to have all kinds of contests and events, which are always going on and can be played for downloadable credits/prizes on PSN. Add an intercom system or some kind of virtual tour guide/host to encourage members to try things out (can be turned on/off). Also add seasonal events (for example at X-mas- areas have decorations, plus ice skating, snow boarding mini-games), include a fully functioning Casino with all the games you might find in Vegas, an amusement park with playable bumper cars/boats, batting cage, race tracks, rides, mini golf, and small arcade, a fully functioning Tony hawk or Skate themed skate park, a golf course, and a park with 2 on 2 basket ball, football, tennis, etc., add pets with objective based mini games (feed, walk, etc), have online terminals in areas which connect you to their specific sites (EA area has terminal that lets you log on to their site directly).
