The only one of these I took part in was the 'Predict how much the Switch will sell' thread, I think.
Looks like I seriously lowballed the Switch, I voted 40-50 million.
What can I say? The WiiU badly conditioned me to expect lower sales, even for a sucessful system.
Well, I wasn't much better, voted 50-60 million. Nowadays I think differently, but that's why these are predictions. So we get our share of juicy crows.
