I know, I know! I simply think PSX is really that much of a cool name..

Well Wii won't ship more than 1million more. Will finish with 102million. PS3 is likely at 84.5million (Shipments) by end of 31st June. Will easily reach 90million+ by 31st March 2015. Still has Destiny, Fifa, Assasins Creed, Call of Duty and Little Big Planet 3 for this Holiday. It won't reach Wii numbers but will finish less than 10million behind.

With a price drop to give it new life in developing countries, and if Sony doesn't discontinue it for the next 4-5 years, I think it could eventually leg it out.

Wii will be off the market by 2016. No way it keeps selling for another 5 years. But that's irrelevant to the question because Ps3 won't make it to 100 million. So if Wii stops selling tomorrow it will still be the highest selling 7th gen console.

No chance.

PS3 down 51% YTD...

It is still very expensive for being almost 8 years old. On the back of slim and super slim and increasing the hdd-storage they (and also MS with its X360) from time to time they did not decreased the price, just gave the customer a little bit more for the same price. And as they killed the old models no one has the chance to get a cheap launch-console, which nowadays would be at 99,- probably when being compared to the current models of PS3 and X360.
When just looking at amazon.de the PS3 is about 250€. Thats incredible expensive for 8 year old console, as it is Wii launch price.
I of course dont know about the production cost but i guess they should be able to decrease the price 3 more times.
-------------------------------------
Early/Mid 2015 --> 199€
Holiday 2016 (10th birthday) --> 149€
-------------------------------------
Holiday 2017 (to clear stocks in 2018) --> 99€
-------------------------------------
I dont know if they really can go down to 99€, but at least 149€ should be possible without generating loss.
Moreover i do not know if this price cuts really have some influence - I guess it is rather a small impact on sales then.

YTD about 1.8 million PS3 have been sold. Last year Nov/Dec have been about 2 million.
For this year i take these 1.8million untill Mid july + 75% of last year sales (3.2 million) Mid July to End of year, so 4million should be OK.
Lets say this year will be 4 million PS3. --> 84.5 million
2015 maybe 3.5 million --> 88 million
2016 maybe 3 million --> 91 million
2017 maybe 2 million --> 93 million
2018 maybe 1 million --> 94 million

That would be a very very slow death and i dont expect the sales to decline so slowly, but even this would "only" manage to bring PS3 into the mid 90's numbers.
I do NOT see, how it can sell 8 million consoles more as it for sure will not sell longer than untill 2018.

So all in all Wii will stay and be Winner in terms of sales for 7th generation.

I just can't see it happening.

The gap is too large.

People predict wii to sell more 4M? that is wishful thinking as well. it won't surpass PS1 ever.

If sony cut the price(maybe a ultra slim redesign?!) and focus on third world countries that,historically speaking,are the last ones to jump on next gen i think is possible.

PS2 sold a lot after 7 gen started right?

If was the summer of 2012 or 2013, I would say it was still in doubt, however not now for a couple reasons.For most of 2013 the PS3 was selling in the neighborhood of 150k a week, sometimes more sometimes less. Now its hitting around 50k each week, that's a big drop off from a year previous. Secondly, I don't see the PS3 having as long a life as the PS2 given the starting price was much higher and profit margin lower, meaning it cost more to make the PS3 than PS2 and the price can only go so low.

When I talk to people about this a lot of them though the PS3 would pass the Wii back 1-2 years but, now a lot less of them do.
