More vaporware
I'm sharing Hardware Unboxed as they slammed Nvidia before and recommended 5700xt at this price point previously.
TLDW: If one can find a 3060ti at MSRP they have found a special card, as with some overclocking base 3070 performance is achievable. More likely the average price of a 3060ti will match that of a msrp of a 3070. Unlikely to find at 525$ CDN more likely 700$, and scalpers will probably ask 1k$
Otherwise its more money that will stretch those scalper funds, and will also not drop in price as it's a very good ethereum mining card. Nvidia may deem it better profit to just supply the virtual currency miners first, and judging from 1060/1070 pricing from 2015/16 we were well into Turing before pricing dropped.
Not a worthwhile upgrade on 2070 or faster cards

The other big caveat is the Radeon 6700 in january??? with 12gb of ram as well as the even more nerfed ga106 3060 cards.
