Wii online soon

Voice chat? Server rooms to join? Adding Friends? Honestly, tell me. Don't just say "everything".

All of those things and more:

-Servers -- general ones as well as user-creatable ones for private areas (like battle.net)
-chat with said people online
-random game option to play with anyone (like they have), but with chat enabled (optional, and hook it into the parental controls to deal with worries about children)
-ability to create custom games, either locked or unlocked, like WC3 or similar games (custom games for just friends/people you invite (who have the password, or just friends, or whatever they want to do) or open custom games for special rules play with powers for the game creator (see: WC3 Custom mode)
-ability to add people you meet online to your friends list
-guild/clan support built in
-chat options -- voice chat, or onscreen keyboard chat for appropriate games; keyboard accessory option would be nice too, though it's very doubtful that they would go that route (text chat is much easier to follow and keep track of in larger groups than voice chat would be, particularly for chatrooms and the such)
-show what friends are doing (darn you Guild Wars, why isn't there a /whereis command? It would be so nice to have!) (hidden mode available if you want to pretend to be offline so people can't see you're online)
-stat tracking -- having it on websites as well as ingame would be great -- re. Battle.net's player records they keep, etc (Guild Wars top guilds ladder online, etc)

And more stuff I'm sure I'm forgetting.
