and chances are it will beat it in the long run. 

Eh, maybe at the end of the day but I'm doubtful it will outsell the Wii even. Though 100mil does seem like a realistic target.

Anyway that is another thread. 17.5mil is my prediction. 

18m next year.

I see a lot of people being back at being safe after the 18.5 millions announcement. So I will go crazy and say 20 millions for 2015 mostly because of price drop and I expect Sony to be more ready for the holidays in the US this time around. They will probably have deals and maybe a temporary price cut for the holidays in the US just to fight against MS insane deals that will be coming too.

Depending on the holiday software, I can see it pushing 18 Million or so. 19 at the max.

3rd parties finally starting to leave Gen 7 behind and Sony 1st party actually flexing muscle. Japanese support picking up. 2015 will see crazy holiday bundles too, so hold onto your butts.

Its gonna be a big Year.

17.5m for a sell through of 36m LTD

I was expecting 20m for 2015 when I was a happy person with dreams, now that I'm depressed in my shortcomings, I "only" expect around 18m for 2015.

I am thinking closer to 10 million behind in the fourth year, but overall PS4 should overtake the Wii. PS console are known for their great legs.

Numbers for the Wii are just crazy, beastly for their first 4 years. I can understand those crazy 200 millions Wii sold and why Nintendo try to do a Wii 2 with Wii U.

18-19million. Alot more system selling games this year + maybe a price cut . Japan might not give it a BIG boost but will atleast sell better then 2014.

19M-20M
