The cancellation of these two Nvidia models that pack more than 10 GB of VRAM might allow AMD to increase its sales, since the Navi 21 SKUs are expected to get 16 GB of VRAM. Nvidia is currently stuck with terrible yields on the Samsung 8 nm nodes, and, once it switches to TSMC next year, maybe it could consider relaunching the 16 GB and 20 GB models.
