I would hope the consoles beat an RTX 2080Ti. (Although there is currently no evidence to support your assertion!)
I dont mean RT is bad, just that on the rtx series is bad, or I would say experimental. Nvidia says they will get 4x the rt performance on Ampere. Im pretty sure they will still be better than amd, but even amd should beat the rtx line. Maybe it was a necessity as devs had something to work with and now nvidia and even amd could work from that.
Or maybe I should ask, will the 2080ti hold up to the 3000 series as well as the 1080ti did to the 2000's? Acording to mores law is dead if people are looking to upgrade and RT is a must for you that you should ignore the 2080ti and a 3060 should be better.
But like you said, cant do much with leaks. probaably wont know untill rdna 2 releases, but nvidia already confirmed that RT wise, they will smoke the 2000's
It takes genuine talent to see greatness in yourself despite your absence of genuine talent.
