Even the just released NVidia Geforce 1080 Ti with a TDP of 250W and a 700$ Pricetag only reaches 10 Teraflops

For comparision's sake: A Radeon HD 5870 is with it's 2.7 TF more powerful than a PS4 - yet it released over 4 years before the PS4, the PS4 Pro is about as powerful as a 7970 Ghz Edition released in early 2012 and the Scorpio will be about as powerful as a Radeon 290X released in Fall 2013. As you can see, there's a 4 year gap between the release of a PC Graphics card and a console of the same power. There's just no way a console released in 2020 could afford (both in price and heat production/dissipation) such a strong console without becoming bigger than the XBO and more expensive than the PS3 at launch. Even a 10TF console is thus only due for 2021 going by the 4 year rule.

Scorpio is supposed to be 6 and it's releasing 2017, why can't it be a bit more than doubled 3 years later? PS4 Pro more than doubled the PS4 power in this timeframe, and PS systems usually have a 8x jump in power from one to another. Which would make the PS5 a 14-15TF machine, launching 7 years after the PS4.
That's what I expect from it.

The RSX in the PS3 was adapted out of a 80W TDP NVidia 7800GT, the PS GPU in the PS4 out of a 150W TDP Radeon HD 7850. 150W is pretty much the maximum a console could take in total, hence why such a big jump was possible between the PS3 and the PS4. But since we reached the limit here in such a small case as a console has, it cannot grow as fast anymore. Compounding to this issue is also the fact that production nodes shrink at a much slower pace since the 32/28nm process, which in the past made such jumps much easier as smaller processes mean less energy needed and thus less heat.

While your way of thinking seems sound to someone less tech versed, it can't stand against a deeper analysis. Like I said before, it's feasible, but not without a bigger case than the XBO has and a pretty hefty pricetag attached to it.
