I'm afraid we aren't the ones in little bubbles. We live in the real world, where there are these things called facts. To get facts, we look at independent tracking sites. You see, we like to know what's going on in the real world, rather than what's going on in these worlds:
the "Real gamers only play Nintendo" world
the "Microsoft is perfect and system failures do not exist!" world
or the "No one will ever outsell a Sony product" world (obviously your world)
