As far as I can tell, in terms of MSRP, 980ti was $649 at launch. 1080 and 1080ti were both $699 when they hit the market.
$699 in 2015 (when the 1080 was new) is ~$975 today, adjusted for inflation.
$975 is pretty close to the launch MSRP of a 5080, which is "just" $999. (We can't actually buy them for $999, of course, but we couldn't usually get 1080 cards at MSRP during the mining frenzy a decade ago either.)
The big difference here is that by the time the 2080 had saturated the market, you could regularly find a 1080 for ~$300 (I paid $275 for an EVGA B-stock model).
Whereas today, with the 5000 series in the market for quite a while already, a 4080 is still well over MSRP

You could say that there was Titan but in practice they were not seriously considered. At least for gaming.
