While the numbers here are likely to be low by over a million going just by the 80 million announcement early November 2013 , it's just not going to leg out that long. Though software wise it will pass the Wii, even then that would leave it second in total software to the 360 and is also unlikely to leg past that either. Though I think it will come within 10 million of both.

While the PS3 won't be able to reach a price this low, it still is sold for US$ 200. There is plenty of room to cut the price, at least until 100 bucks. Its sucessor is also more expensive. During the PS1 final years, a PS2 was most likely costing 150 dollars, so it had to be cheaper. The PS4 still is sold for 400 dollars, so a 100 bucks PS3 is similarly priced. The PS3 also isn't yet with a good pricing on developing market. One PS3 on Brazil costs R$ 800, while both the PS1 and PS2 had their final years with prices lower than R$ 400 (R$ 3,10 = US$ 1,00).

We can also assume that this gen can be as long as the previous one, so the PS3 would have many more years on the market.

No, never.

The only way it will happen is if they sell PS3s at $50 for the next 5 years.

Selling only 10% less than the Wii is already a huge achievement honestly, considering the hype the wii had. And besides there's the price, PS3s are still quite expensive for what they are and the age they have.

you assume so, because the tech in it is old, but I think if Sony still had the option to cut the price then they would have done so last year

by this time sales of the hardware have dropped off a cliff, which means that the price to produce an individual unit has gone up instead of down in the last months especially as there were no further shrinks to the CPU/GPU and XDR ram is super rarely used (hasn't decreased in price), so I think that a price cut of even $50 would make it unprofitable to sell it - Sony won't sell it at a loss at this stage, they'd rather phase out production completely

I think they still have plenty of room. They redesigned the console with the super slim model and basically it sells for a similar price point (except for the ridiculous 12GB model). They wouldn't expend R&D with a redesign if it doesn't helped when cutting costs, so we can assume that it's considerably cheaper (they wouldn't do it for aestethics, specially because the super slim model is uglier because it is visibly cheap).

The fact that th XDR ram isn't used doesn't make it expensive. Most consoles before the PS360 year used custom components that were only used on them (PS2 emotion engine, N64 RAMBUS memory, etc), so it's pretty much the norm.

They also redesigned the Vita, cutting costs, and stil it didn't suffered a sizeable price reduction, even if its situation is more dire than PS3's one. They don't seem much interested in price cuts and probably are just trying to profit as much as they can. Despite that, froma technical standpoint, we've seen consoles with hardware choices much more exotic reach low prices (Sega Saturn).

Again, it isn't nowhere near the price point that emerging markets expect. 360 also retails for a similar price, so it also has plenty of room for cuts. PS4 and X1 are way, way to expensive. I think that a cheaper PS3 could be a good option if they advertise it with PS Plus, because it gives you plenty of games with a small fee (PS Plus in Brazil is R$ 100 or around US$ 30 per year). PS3 digital sales are also way more generous than PS4 ones and I've bought titles like RDR, Spec Ops and Motorstorm Apocalypse for values between R$ 10 and 30. PS3 is, currently, a much more cheap console software-wise, they just need to cut its price.

In this thread there are a lot of people thinking it won't sell anything from now on. Most of these people live in US or western EU, where consoles are cheap and people jump early to next gen. Emerging countries are different. A lot of guys are STILL on PS2 and are just waiting for a cheap upgrade so they can play Fifa and CoD.
