Since when does every generation have to be better than before?
There will be slips eventually, there will be controversy, backslash, and other problems big and small. With the rumors of mandatory internet connection, used game banning, etc, so many people are downplaying the rumors as false even though we've seen these trends slowly creep in other forms of technology we use everyday. Sure, keep on refusing to believe these rumors, but what IF these rumors are a reality? We are a few months from finding out.
And when these rumors are true, the whole industry will be transformed, maybe for the better, probably for the worse. Each gen added something revolutionary to the table, while also removing what we loved. It's going to happen again.
