I'm not expecting that, if anything they will be less expensive.
The "conventional logic" that is being applied here would suggest that a xx80-ti should be at least £3k by now. Just look around this section of the forum and see how many complain about price, see how many have refused to buy at that price, and how many who did buy at that price are now saying that it was an upper limit for them. There were 3 big factors pushing GPU prices up at the time; Cost of components, new technology (RTX) & GPU mining.
There are actually now factors pushing prices down; RTX maturing, component cost lowering, mining has waned, console competition, possibly competitor competition.
I would also say, don't pay any attention to the model variants and just focus on the performance you actually need.
