I said February 2015.

PS4 have sold more than 10,000,000 now, and i predict 18,000,000-18,500,000 by end of 2014.

So, on Jenuary and Febrary with The Order, The Witcher 3, and Evolve, will easy sell other 1,500,000-2,000,000, maximum on March.

And for you when PS4 pass this number?

March 2015

Really hard to say. The 2015 line up looks absolutely stellar, but 2014 holiday is week, just like the competition though.
Don't think it will make it by March, would love to be wrong though.

February 2015.

I think early to mid next year, probably around when Bloodborne releases. If sales really take off before then, maybe early next year around when The Order releases.

Agree.

Around March, I'd say.

It seems your numbers get bigger every time you post here^^

Not impossible.

Ineed, PS4 sell much more than i have expected, so, my prediction of 170,000,000 PS4 by end of generation is always more probabily! XD
