ps2 had so many good conditions going for it from weak competiton to incredible dev support, good price point, long support by sony/devs not to mention the ps3 launching with a insane price point causing ppl to not jump the gun so soon to the ps3 gen ect ect.

this cycle will be 5 1/2 years atleast,im hearing shorter but why would sony release a new gen any earlier when they did so much right by the ps4? this will be a heavy part of their focus for 5+ years as it should be,but not as long as the ps3 before releasing another system....this should be their focus for a length that was about equal to ps1 and what they wanted the length of the ps2 to be before releasing the ps3 that was having blue-ray diode problems causing a year delay.... anyways 110-120M....

I will just go on my typical spiel.

PS4 and XBO are changing the face of video game consoles even more than PS3 and 360 did. In fact PS4 and XBO are not Video game consoles and never have been marketed as so. They are All in One Computer Entertainment devices, or set top boxes + games. PS4 and XBO with the introduction of Over the Top Television, are capable of replacing every device under the TV besides the audio reciever. PS4 and XBO are a Cable/DVR/On Demand/PPV box, they are a Blu-ray/ Streaming Services Box, they are a set top box (Roku, Apple TV, Amazon Fire TV, etc.), and they are a current gen video console/gaming PC. With the help of the web they can nearly accomplish any task the average joe does on a PC, and even those tasks are coming via native apps.

In the US alone, it is estimated that there are over 160 million active cable/satalite boxes. This means PS4 and XBO have a shot at massive numbers in the US alone. It is possible to see 100M PS4 and 40M XBO or 70M and 70M, they could become the whole television market and split the whole 160M. This is just one region, and one of the many reasons these console will blow past their predecessors. Once more and more productivity apps start hitting the consoles, many people will find that more effecient, simpler, and faster than their home PC/Laptop, and this will cause even more sales. Then there is th mass expansion in India, China and other global markets.

As I have said before I expect PS4 and XBO to both be the best selling devices their Brands have ever produced. 200M PS4's, and 100M XBO's are in the bag. This generation is not going anywhere soon either. It takes three to four years to develop a Triple A title, and it take 2 or 3 of those before developers reach the point of deminishing returns. That is 8 to 10 years before a new generation is even neccisary. Then we have the massive slow down in advanced manufacturing. This means we will not see hardware with any kind of quantum leap tell at least 2019 or 2020. Unless MS and Sony decide to do incremental consoles at each die shrink, we will not see new consoles tell around that time.

If Sony ships 95 million I can promise you that they'll pressure retailers into taking the remaining 5 million it takes to get to a hundred. They'll do it just for a marketing ploy. Heck, they'll probably push so that they outsell the Wii and the PSOne so that they could say "The PS4 is the second bestselling video game console of all time, the bestselling one in the last 15 years" 

Did anybody really believe this ?

PS4 will sell something between PS3 and the Wii. I'd say LTD sales will be around 92M.

PS2 was by far the weakest console of the 6th gen, PS4 is very clearly the most powerfull console of its gen

Don't fall in OP's trap. At first he made unrealistic target which wont be possible (I know none can beat PS2's number). Now he is downplaying PS4 with his changed target.

PS4 will sell 120-130M.

Too early to tell for sure, but it doesn't just depend on weekly and yearly sales indeed, but also on how long they'll last. This could be used as an advantage, though, as using PC-like architecture and components, if Sony wants it will be able to cut price down to very low level, opening new markets and widening the target in the existing ones. But the ability to do it alone won't grant it, it will depend on the strategies for the next generation switch too, and not only Sony's ones, but also those of its competitors. An early start of next gen will almost surely lower this gen's potential, although if any competitor will decide a too early and half-assed start, the other two could resist with the current gen and totally crush its head start advantage launching their next gen consoles at their planned date, more mature and powerful and possibly more reliable too and at the same time less expensive to build.
This said 170M is very unlikely, while 110-130M should be a lot more reasonable target and 140-160M an unlikely but not impossible goal if almost everything will go right and the generation will last enough.

I didn't realize people were thinking it would beat the PS2. Beating the Wii and PS1 is possible; but not much more than that IMO.

C'mon homie "Jenuary" lol I cracked up reading that. Albeit it could be a typo for all I know.

OT: Yeah I doubt it'll surpass the leviathan that is the PS2 but I do think the PS4 will sell 100+ Million.
