I actually think they aren't too far off on Wii U's sales, but I think it'll be more in the high end of their prediction. I think 50-70 million seems more likely. I still see Wii U as the Super SNES to the Wii, so I think it'll sell about 2/3 the numbers Wii managed, like the SNES did in comparison to the NES. Also, even though sales will be underwhelming compared to Wii, Wii U will be more of a slow burner. Using the current trends of Wii U sales will not help as it's far too early, price is still high, and very few significant games have been released. There is a major flaw in the thinking that Wii U is "similar to this gen consoles." Do this gen consoles have a tablet controller? Do they have Nintendo games, or even many games similar to them? Although the numbers I don't believe will be far off, their reasoning behind them are.. But then again, it's Patcher, what do you expect..
They highly overestimated PS4 sales IMO, and NeXbox is probably close to reality. I see Sony as a company on the decline, while MS has gained a lot of ground from last generation. They have effectively taken over the US market, the biggest gaming market, and have the UK market, which is probably the largest in Europe. Sony has Japan, which is a dwindling market, and some portions of Europe, which is going through a major financial crisis. PS4 will also probably be the most expensive console yet again, which will set them back a bit sales wise. But again, still way too early to say, especially since MS hasn't even revealed their cards yet on the 720.
