Currently the PS4 has thirteen games that have sold more than a million, six games that sold more than two millions and two games that have sold more than three million.

Given the release of big name titles like Assassins Creed Unity, Far Cry 4, Grand Theft Auto V, Dragon Age Inquisition and Little Big Planet 3 and a couple of games near a million already I believe the PS4 has a real shot of reaching this milestone.

What is your opinion?

20 is a given, 30 is more interesting.

Theres 15 more that will more likely then not hit 1m this year.

I'd be more inclined to say it'll end up between 16.5-18 million.

Edit: I read the question as will PS4 have 20 million consoles sold. Yeah I can see it having more than 20 million sellers.

lol missed the boat on this one.  

Yeah I just reread the title

Easily, might be looking at 25+

Wonder if we'll get a game to 5 mil this year.

Cod probably, holiday sales and massive marketing.  Plus it actually looks good.  

Guaranteed to reach 1m before 2015:

Ground Zeroes
Madden
CoD:AW
AC:U
GTA

Those games already bring the list to 18.

Probable 1m sellers:

SoM (best selling LotR game in the UK to date).
FarCry4 (FC3 did 1.5m on PS3 with two less weeks than FC4 has)
LBP3 (holiday game)

Already at 21.

Other candidates:

The Evil Within
The Crew
Whatever other games I might be forgetting.

So yeah, I think 20m is guaranteed.

If it does not do at least 20 million sellers I will lose a dreadlock.

20 million in software should be easily reachable by the end of the year. Holidays will be massive.
