It took the 3DS less than 4 years to cross the 50m mark, so I wouldn't rule out the chance of PS4 reaching the same in 3. It's not easy, yet it's not impossible.
Bet with Teeqoz for 2 weeks of avatar and sig control that Super Mario Odyssey would ship more than 7m on its first 2 months. The game shipped 9.07m, so I won
