W5700X is expected to come soon in the MPX module form but I see another option for W5700X. I dont know if it looks like Vega 2 Duo or not but I assume it might be.
I'm not sure what you meant by this. The new W5700X coming in MPX format will have the fingers on the top of it for the bridge that allows two units to be installed in the Mac Pro.
Yeah I wish they would announce rough timeline here. Some people *cough* are waiting on ordering for these options. If it's early January that's one thing, but if it's sometime in the spring, i probably won't wait.
Are there any signs of the Radeon Pro 5700X in the latest betas? If not, coming soon could be several months away
