It would be cheeky but humorous if PowerColor would lean hard into their Devil branding and go with a 6660XT Red Devil and 6969XT Liquid Devil edition, which would just be specially binned chips with better performance than the "regular" batches, somewhat like like special silicon used for the "6900XT Ultimate" editions of some 7nm 6900XTs (the XTXH bins). I mean, if they're just going to add xx50 to whatever just to denote a higher performance variant, why not just just be cheeky about it and pick 60 and 69 instead and fully lean into the not-exactly-subtle theme, since it's not like AMD would further sub-divide into single-digit increments, and bigger numbers tend to sell better to the masses.
On a similar note, I'd like to see Sapphire do an Atomic variant of the "6950XT" as another waterblocked GPU similar to the Liquid Devil and other similar equivalents, while also upgrading a theoretical "6950XT" Toxic to a high-end Hybrid AIO card with QDCs from EK or AC for expandability and upgradeability (able to substitute a larger radiator if the case permits).
Then ASUS could also follow with reviving the ARES branding, for waterblocked cards and later, dual or multi-GPU single cards (like the chiplet GPUs AMD is said to be working on), that are specially binned as well.
