With Media Create numbers out I can finally finish this.
Predictions: (actual)
Week 47: 140k (108k)
Week 48: 120k (120k)
Week 49: 310k (281k)
Week 50: 180k (281k)
Week 51: 290k (278k)
Week 52: 140k (175k)
Total: 1.18m (1.24m)
In the end a very close result. And as the lowest predictor, I believe I can say that most people expected more from Switch during the holidays. Even I expected a 300k+ week, but that never really happened. The margin is close enough that even though I slightly underestimate Switch, it was pretty much spot on.
