Depends. From the looks of it, Sony is able to make the PS4 dirt cheap. You can get one right now for 180 € around here. If the price continues to fall, sales will rise. I think it isn't impossible for us to see PS4 retailing for 149 € sometime next year, even when the official price recommendation won't go that low. Still, with such a low entry price, I can see the PS4 actually rising in sales yoy. Something similar happened with the PS2, if I remember correctly. That console sold I think only 10 million in 2004 just to sell 20 million in 2005, because of ridiculous low prices. I grabbed one by that time for 89 €.
Long story short, it all depends on price and it's looking good. The PS3 stayed expensive forever, it never got really cheap. Hell it didn't even ever get as cheap as the PS4 is right now, not even with that silly 12 GB model. Scorpio will only help to make the price tag of the PS4 lower. I can see the PS4 outselling the Wii by the end of 2019. Maybe even earlier, but not later.
