Obviously HOME would be on the list in the next major ps3 update. but what other things could make a difference. mine are:

1.being able to change the colour of your friends name when they sign in.
2. different avatars that dont suck.
3.being able to change the colour of the PSTORE when it gets the new look.
4. having more friends online.

when i thought of this i had more, but thats all i can think of.
