Well, let's have some fun predicting. WiiU has a year headstart, but it's sales are not great. So how long will it take until PS4 and XBox One have more units sold to customers than WiiU? Post your prediction in weeks. I will try to add it to the OP. I myself say PS3 will need the second christmas, so 65 weeks. Xbox One will need longer, 100 weeks. What do you think?
