Well, it's because the Wii is obviously going to win this generation due solely to momentum, even if its competitors have the opportunity to catch up. This means more of the major games will be hitting the Wii once the devlopers catch up, and the system is going to end up with a fantastic line-up. Many people are going to end up with 2 systems anyway, and if you have one one of the HD systems already (or plan to get one when they are affordable) you probably won't see too much to draw you to the other unless you like more of the same.
You do not have the right to never be offended.
