The next PS and Xbox will have shitty marketing, no mainstream games and too high of a price? Uh huh. If Microsoft does one thing, it's market the hell out of their products. They won't pull a Nintendo. Mario isn't mainstream? Nintendoland isnt? How about Just Dance, FIFA, Madden, Assassins Creed, Batman? There was plenty of mainstream games at the Wii Us launch. Price was high compared to the competition, yep. My time machine is broken, so I can't tell you what the price of the PS4 or Xbox will be, or what games they'll launch with, but I guarantee you they'll launch with mainstream games. And plenty of them. I have no idea what you're saying is biased given the context of your message.
The 360 came out on the heels of a last place console and sold pretty well its first year. It had the market to itself, just like Nintendo has the "next gen" market to itself right now, but they're coming off one of the most successful console generations anyone's ever had. To have to reduce their sales estimates a mere 2 months into the lifecycle is kind of the definition of "doing as bad as people make out".
