Exactly.. Just wait until the bad boys like Gran Turismo and Uncharted come out... The PS4 will really be killing it..

I agree. I think it will end up at around 90 million.

I only go on the financial reports since they are the most interesting historically.

You are right about the releases, and I should have thought about it. Sadly we don´t get breakdowns per region, it would have been more interesting. It still looks really good for PS3 sales though since those aren´t bad numbers in any way.

PS4 should be able to clear 100M with ease. It is well ahead of 360 in both of its first 2 years on the market, and destroying the terrible start of the PS3. To put things into perspective, 360 did not hit 8.4M units sold tell January 27th 2007 according to VGChartz.That is 62 weeks after launch. PS4 has already reached this mark in 34 weeks, and ahead of its second holiday. In 2007 360's second year, it was still selling at a slower rate than PS4 currently is seeing.

Looking into the future PS4 has no known surprises ahead like the launch of two new competitors. Unlike PS3 and 360 PS4 is already making money at the hardware level, and is in a much more PS2 like position where Sony could Knock $100 off the price at next years E3 just like they did in 2002 with PS2. Next year will also see the return of Sony's biggest franchises, along with a much bigger out put from SCEWWS overall. PS4 will be at the forefront of both IPTV, and VR displays, two things which have potential to blow up sales as the generation progresses.

On the negitve side of things (why it would not hit 100M). Microsoft have already stated that Windows 9 will be marketed as the One OS. It is suppoed to unify PC, Tablets, Phone, and XBO. If XBO gets access to all windows phone apps, and Sony has no counter, this could be a major turning point in the generation. Over at Nintendo, if they really move to a single system home a mobile device, and compete in power by 2016 or 17 it could really hurt sales in the later years. Finally, there is the outside chance Steambox, Samsung, Apple, or Amazon could put something out that steals marketshare.

Whilst I agree with most of what you said about AAA developers/publishers, it's also not true for all AAA developers/publishers. The three companies I gave in my previous post are all working on multiple franchises with different teams on each. It also depends on what each studio/team is doing. Most big AAA games still only have one studio working as the primary, with many other studios pitching in as secondary studios. Many of these will be working on multiple games but just happen to have the expertise needed in a certain area to help out and whilst it adds a lot of names to the credits, it could only account for 10% of their resources with 90% on other games.

The other thing about Indie devs is whilst right now they may not seem worth a $400 console, these are the AAA devs of tomorrow. They're the ones that will come up with innovative ideas and who will later get contracts with publishers along with bigger budgets. We're already starting to see this with the likes of Project CARS so by year 3 of this gen, expect a lot more.

Its slowed down because thats how the yearly cycle works. And while its not doing amazing, its lowest weekly is 98k compared to PS3 which was doing 60-116k during the same period in its first year.

What matters is the yearly peaks at december and it took PS3 3 years to get past 660k sales per week near december. The PS4 will be doing way more than that every december for the next 6 years and non holiday sales will get better when the true next gen games start coming out and it gets a price drop.

It is common sense that it will pass 100M by far, it's the console that will gather everyone, the market wont be too much splitted so 100M is the low expectation.

Yes if 10 years but 7 years i don't think so.50 to 70m in the lifespan.

Seriously? Please before you say anything like this, actually look at the numbers.

DS had a baseline of about 100k in its first full year (2005). Comparative week in 2005 (July 9th) 99k, after adjustments are made that will be lower than the PS4. Believe it or not the PS4 is selling better than the DS at the same point in its life, a handheld which sold 150m+

PSP had a similar baseline in its first full year (2005 again). Comparative week = 88k. PS4 is better than PSP as well

X360 had a baseline of lower than 100k in first full year (2006). Comparative week = 76k PS4 better again.

PS3 also had a baseline of lower than 100k in first full year (2007). Comparative week  = 59k. PS4 is doing miles better than PS3.

Wii had a very high baseline in its first full year (2007) as we all know. Comparative week = 248k. Wii was doing amazingly.

3DS had a baseline of about 150k in its first full year (2012). Comparative week = 132k. Its beating the PS4 slightly but bear in mind it had a much longer launch year.

Only the Wii was doing better than the PS4 is doing now in the same time frame after launch, 3DS was doing better weekly at the time but it had many months longer on the market so that is expected. PS4 had and still is having an amzing start, especially considering the lack of exclusives. I'll be very shocked if it doesn't reach 100m.

Too early to tell, but in favour of PS4 there is its PC-like architecture and components that will allow Sony to regularly drop its price at the right moment without problems, so as long as games will keep on coming, sales will come too.
This applies to XBOne too, as it has a PC-like architecture too, but having chosen a more expensive APU and having included the expensive Kinect 2 for the first months, it had a steeper path at launch, it had to "waste" a major revision early, ditching Kinect from standard equipment, so it could have a long life too, but with lower sales.
Wii U is still the cheapest, despite the expensive controller, and it has the games Ninty fans want, so the problem must be mainly in marketing (BTW MS and Sony can have either excellent or awful marketing too, so they both are still in time to damage their products, MS already did it before launch, just like Ninty, and Sony isn't Sony anymore if during 8th gen it won't make any of its marketing blunders too ).
