No you are oversimplifying something that is not simple and pretending it makes it a trend. Each of those cards launched with a very different performance relative to the other cards in the market. Just going simple 560 Ti vs 660 Ti. The 660 Ti is 20% slower than the 680 and it's based on the same chip, you get 80% of the performance for 60% of the price. The 560 Ti was 40% slower than 580 and based on a smaller chip, you got 60% of performance for 50% the price. It's a completely different animal. The real mid-range the non-Ti 660 based on the smaller GK106 will launch soon and for $250 or less. EDIT: I also fixed the launch pricing BTW.
