In that range, it will be 15-20% faster than 2080 Ti, making it almost on par with upcoming 3080 if NV maintain their usual performance cadence.
I don't know about a WC version, and I doubt they will ever make another consumer side dual GPU. You do remember the fiasco of the 295x2 right? 1500$ that went to 1000$ that went to 750$. It was a bad GPU overall. And with lower and lower support for multi GPU in games, I don't see AMD or nvidia releasing any dual versions (maybe a devil version that won't be a manufacturer card).
15-20% faster than the 2080 TI is a doubt still for me. The 2080 TI is about 50% faster than the 5700XT at 4K. I mostly expect a 2080 TI performance because even adding 100w and making it a 325W card (which I doubt), it will still not be enough to handle the amount of heat it will produce, so they will have to hold back the card.
A WC version might be matched to the AIB versions of the 2080 TI as well. Nvidia OCed is still pretty good once put in WC and temps are kept in check.
Things might also be very depend on time. If nvidia release their next series before AMD's new card, or on the same time, they could take AMD's thunder. If we will see a 2070 super replacement matching AMD's new big navi (which is what I expect considering 2070 and 1080 TI), it will completely take the carpet from under AMD.
Personally I think AMD will release a new refresh (like they did in polaris 3 times) and add a bit bigger card, and keep for now on the mid and low range fight. I don't see them fighting nvidia for the top end. But they might surprise me (though still, the 5700XT at 225W, even with incoming 7nm+, it is too much heat and power to have room for a big card).
