If Nintendo adds a channel that allows you to chat with Wii Friends (Not adding new Wii Friend Codes) then this will be a great addition. It would mean we could go into a channel see our friends and select people to talk to and create a room.
Now, if Nintendo can do this, and then allow that Channel to remain open while playing games...WiiWare, VC, or even Wii games then we have a THE SOLUTION, to voice chat being absent from every game up until now. Heck, you could even voice chat in non internet games then...how cool would that be?
Now, the question is...how possible is it that Nintendo would
1)Make a WiiTalk channel (I would say probably 100%)
2)How possible is it to play other games through that WiiTalk Channel. (I would say much, lower. Like maybe 50%) It would at least need a completely new firmware update to allow that to happen.
