I don't see WoW hitting consoles ever, console cpu's are not strong enough to handle 20/30 man at 4K resolution.
Gotta remember the biggest bottleneck in wow is the CPU, and in consoles the raw CPU power is compromised for more GPU power.
I mean even the XBOX one X and PS4 Pro are barely on par with outdated intel quad core CPU's (as in 8-10 year old models).
