3.3 million in 3 months? That's pretty good. Probably gonna end the year at 72~75 million if the holidays hold up well.

Sony stated that they were returning to a more typical generation length, the previous one was protracted because it took the playstation 3 so long to be profitable, so I think 6 years is about right. 

I think the PS4 has peaked already, I suspect that total year sales will go down this year and the next enough to justify a 2019 release for the PS5, it's nothing to do with XBox One X, it's not a legit threat to the PS4. Before you sony fans burst a blood vessel, this is just my opinion, I could be completely wrong.

Wouldn't be so sure about that. Gran Turismo, God of War, The Last of Us 2 or even multiplats like Red dead Redemption 2 will all make a lot of people buy PS4s who don't own one yet (even if it's just a 199,- Slim.

I am predicting sales, not shipments.

When you're talking the lifetime sales of a console until discontinuation shipments ARE sales.

That would only be true, if a shipment equaled a sale, it doesn't.

It's true because consoles always sell out of their shipments, have you ever heard of a console that shipped units that never ever sold? It doesn't happen. Lifetime shipments of a console = lifetime sales.

Any figure given for past consoles total sales is shipments. The only reason shipments don't equal sales during a console lifetime is consumer sales dictate the speed of shipments, so you can overship, thus consumer sales give a better indication of a products momentum. Lifetime you do not overship.

Sony's prediction is to be down by 2M from last FY. This report is the first for this FY and they are only down by 200K.  There is little chance they are going to drop 1.8M more in the remaining FY.  Even if they drop 200K each quarter, that's only 800K down for the whole FY. In other words, Sony was being slightly conservative with their forecast.  

Personally, I only see them being down by 1M, so they will be have sold 79M by March 2018.  Do you seriously think that the PS4 is only going to sell 13M for the remaining 3-4 years it's on the market?  Come on, be realistic.  It'll sell 13M, at the very least, up until the next FY is over, March 2019.

The PS4 is outselling the Wii.  Just like the PS1 and PS2 did.

It will be the second best selling Playstation system when all is said and done, only behind the PS2.

So they shipped ~1.1M per month? Holy crap that's amazing, very good job Sony!!!
