Let's see. the ps4 has been on the mark for the past 15.5 months according to the last time vgchartz was updated, and has sold 20.5 million units. Given that second and third years tend to sell more than the first, I don't see how 30 million in 18 months is unreasonable. I'm not saying I think it's a definite, but it's certainly possible.
