1. Isn't console wars talk forbidden on Resetera?
2. An evergreen title can't suddenly increase it's sales by 500%, cuz it is actually an evergreen title. If you sell well over the whole year, chance is that everyone who wanted the game has one and only new owners buy into it.
3. The Switch is actually doing fine right now and will most likely by current calculations hit their 20 million goal worldwide. It will be rather close, but they will hit it. Also, Switch is doing fine for a console that is basically not discounted at all at the 1 and 1/2 years point. After 2 years for example the PS4 had it's first discount. And as far as I know, Switch is still ahead of PS4 if you compare both from day 1 to 1 1/2 years.
