I guess ill explain a few things in a simple way:
Exclusives will bring people to a console wether its 1st party or 3rd party, and it will benefit the console maker double if their 1st party titles are the main attraction as they make a big profit on game sales aswell as producing more console sales.
The reason people say wii 1st party titles dont count is because some people dont like the type of games nintendo produce, for THOSE PEOPLE ps3/xbox360 has a much better line of exclusives and therefor they will want those consoles to "win" until wii can show them the type of game they like aswell.
So both people sides arguing in this thread are correct depending on which perspective you are looking from.
