I *really really really* hope Nintendo recognizes the popularity, power, and importance of integrating online support with the Wii. If they are so worried about paring up 10 year olds with Johnny the Kidnapper, they need to focus on parental controls. Like I have suggested before, have parental controls on the hardware side (which I already believe they do), whereas a bit is either on or off depending on the setting of the controls. All the software has to do is check that bit before enabling or disabling certain features (such as chat). It can't be that hard, can it?
And game demos all the way. You know, I wouldn't be *terribly* surprised if they do this, especially considering the DS Download Station game demos and such. The only concern would be the amount of internal memory available on the Wii. I don't think 512MB (minus the space taken up by saves and other stuff) would be enough. I guess that's where the SD cards come into play...and hopefully they actually do something with the USB ports (or are they going to be this generation's version of the SNES expansion port?).
