Amazingly fast. It'll be at around 30 by the end of the year surely, or at least close to that. Next year should be huge as well with even more new million sellers and multimillion sellers.
DriveClub is already above 1m!! Amazing. Decent word of mouth from now on should help its leg.
Interesting that FIFA 15 can potentially outsell CoD: AW, but it's hard to call right now. That has never happened since CoD got huge.
Infamous above 2m+ is a nice sight.
TLoU is already huge on PS4 and not many expected it this quickly. It's amazing how Naughty Dog always manages to surpass expectations
At this point it's looking like almost every game on PS4 reaches 1m 
. If it's decently big it will get there. LBP3 will probably get there this year with some oomph
