We are talking about different markets. When you say that the 3090Ti wasn't "worth it" to people who already had 3090's you are refering to value. If the $2k 3090Ti was for the people who "only want the best" regardless of cost or value for money, well what it's "worth" doesn't matter.
The only thing that matters to *that* market is "Is it the best?" It was the best and we saw how big the "best at any cost" market was after crypto mining tanked. (Not that big)
I disagree. There are plenty of enthusiasts on here who will only by the xx90ti or if the xx90 offers a big enough gain and they dont want to wait, they will get that. Very few will then upgrade to the ti later.
With the shortage and prices rising every day, many people like me decided to grab the 3090 for this gen. I am a person who have had ti's and two titans in the past but I only ever buy one card from each generation, I would never upgrade within generations.
