Im kinda suprised they haven't mentioned plans to further there SIM type setup. We got as far as Mii's interacting with eachother "way before PS3 Home was started" now they just need to up it a notch and give us better online community for the Mii's to wander and play in.
I'm sure something is in the works like that already.
Mii's: Busting out anyone? ha ha
