That's some pretty silly logic.

The PS3 and Xbox 360 were engineering marvels of their time, ahead of PCs even for a few months; the Wii was a marvel as well for other lesser reasons. Factoring in how much people are willing to play their ps3/360 instead of getting a next gen consoles compared to how quickly people bought the 360/ps3 when they first came out, it's pretty obvious none of these console will reach 100 million..

What's changed from the last generation console launch: Steam, Steam-boxes, buildable PCs that cost as much as these "next gen" gaming consoles, the WiiU, continued support for the previous generations secondary functions that didn't exist even when the 360/ps3 were initially released..

Also, people bought a ps3 because it was only $150 more than a bluray player at the time... think about that.

Thinking to the future, Virtual Reality.. We need 4k resolution at least to make a decent looking oculus game, please tell me right now you think the ps4 can push 8 million pixels... I'd love to hear someone say that.

DVDs were affordable by year 3 of the PS2s life cycle (and as ubiquitous as video streaming services today), so by that point the PS2 was a pretty expensive DVD player if you wanted a primary DVD player. The whole DVD selling point only really helped push the console for the first year or two. By year 3, even myself as a poor 18yr old student had access to 3 pieces of electronic equipment that could play DVDs. 

The strange thing is you're right in that PS4 doesn't have a truly unique selling point. Only a few major exclusives, upper-mid level PC tech, streaming services similar to the competition and it's not even the cheapest console on the market. Yet it has still sold a ridiculous number of units.

Going forward, if Sony did nothing to rectify this then the sales would drop, but we know they have things in the works. We've yet to see the impact of VR or the release of major next-gen exclusives. And as is the course with consoles, Sony will have unannounced projects and will release hardware/software to expand on the consoles capabilities thereby extending the lifetime sales of the console (as will Nintendo and Microsoft).

Now, will it push past Wii.. yes I think it will, for the simple reason that Nintendo pre-maturely stopped Wii software support. The Wii could have sold so much more than it did, but sales fell off the proverbial cliff after year 4 due to a lack of support. I don't see that happening with PS4. Why? Well, GT7 probably won't come out until year 4 anyway

I also think having SD only hurt Wii's legs.  People just felt like they were buying old tech when those big bars would be on the side of the screen and the Wiimote really wasn't great for traditional games.

I think the next gen starts in 2020. Which means this gen will last for 7yrs. On the 6th year we will start hearing or seeing stuff about the 9th gen consoles though. Maybe even nintendo releases early again and come out that year with sony and MS to follow. So in a way I agree with you and don't too. The decline in sales of the previous gen has nothing to do with an industry changing. Console sales can't increase forever, sooner or later they will reach a saturation point and software sales still remained strong. GTA5 sold over 30M copies afterall.

Funny thing about PSnow, is that if its used the way you think sony would use it, basically allowing you to play PS4 games even if you don't have a PS4 (which I don't think they would do) it would actually lenghten the life span of the PS4 not shorten it. Cause it basically means that as long as you are willing to stream and can, all you need is to buy a PStv for $99.
