Sony would have to produce a product that was cost neutral or cost positive at sale to have success using a model similar to Apple.
Agreed, that's why I said as much:

Producing bleeding edge hardware at cost...

...while having the new ps4 be a scaled Cell with a mid-grade Tesla GPU that could be sold for break even
Otherwise, Sony's hardcore and core userbase would be a negative for Sony and not a plus. Hardcore and core users will likely have the shortest time of ownership as they jump to console to console every two years. Currently, their average time of ownership is probably the longest of all console owners. As they are most likely to be early adopters and least likely to abandon a console until the next gen launches.
As I said, as long as they are break even on hardware, the plan would work fine. Gen1 hardware will eventually get cheaper to produce and allow a smaller box and a smaller pricetag while still not being a drag on Sony after the new gen2 hardware launches at cost.
Also, Sony already employs two tier product cycle where each console is given a 10 year life. A two tier system where the product cycle is cut to four years means instead of having two skus over a 10 year period you end up with 5 skus. A two tier system doesn't make sense with such a short time gap between product launches. You can't expect your whole userbase to migrate to the latest two sku every two years. Developers are going to naturally want to target a large swath of the userbase meaning they may have to accomplish that by targeting at least 3 PS skus for every single release.
The 10 year lifecycle becomes redundant with Sony reestablishing the Playstation platform.
If a developer wanted to, they could get a ps1 devkit and get to work targeting that platform knowing that all future and existing Playstations would be compatible with it.
The concept is very similar to PC development with the advantage of not supporting literally millions of configurations and not being forced to target a baseline comprised of motherboard embedded dx7 Gpus and 10 year old cpus.
The baseline config is up to the developer, but it would have to be made readily apparent upon purchase what hardware is required.
ps1
ps2
ps3
ps4.1
ps4.2
ps4.3
ps4.4
etc.
Until and unless a drastic new hardware is required which is powerful enough it can also run all the old ps4 games. Which if they deem it necessary to replace the ps4 arch, it should have no problem emulating the existing ps4 arch. Otherwise it seems it would be a bit pointless and scaling should continue.
...or onlive-type replacement becomes a possibility.
So over a ten year period you end up with 5 product launches and 5 consoles that have 60% of their lifespan removed. The only way this happens is if Sony launches consoles that cost $150 to make but retail $300 dollars or they market all their product launches with door hangers and youtube videos and ship their consoles in paper bags.
No lifespan would be removed.
Same games, just with added or removed features.

All games made for ps4.x would play. Just that some would obviously look/sound better than others.
At some point there would come a time when the base processing ability of the ps4.1 console could not handle what the top end ps4.x console could do
function wise, and at that point, a new console family would need to be produced (ps5.1) ... or perhaps a live streaming gaming service would be viable by then.
