Erm according to which coders? I only have the xbox devkit at the moment but the previous title I worked on was multi-platform and if there's any difference it's very marginal. You're basically back to the argument "The Pentium3 is clock-for-clock better than the G3!!!!11!!!1!". No seriously the biggest problem with the Wii and the GC before it was simply the devkit and dev-tools themselves. The IDE and libs just weren't as solid or as well thought out as the XBOX by the long way. That said I know that the Wii hardware is as good as the XBOX (1) hardware because I've developed games for both!
I didn't say that the Wii was a fair 7th generation console but defining it by what resolution it can output isn't exactly fair! :lol:
