is it possible to have an ETA for those 2 products?

Wireless Wire nRAY has been announced few months ago but not still availabe at distributors, it seems to be vaporware
CubeG-5ac60ad non yet announced but is a great product Q4 2020 or 2021?

We need to plan our networks so a roadmap is very important to choose between products and brands.

Thank you in adavance

Not this year

Lessons learned when working with Mikrotik: Never plan to use any future/unreleased hardware that's just announced.
It may take year(s) or more from when device is announced and before it's available for purchase. And it's getting even worse this year, be it COVID or something else.
Also never trust datasheet specifications, always test all features yourself before you decide to use specific device or order some more.
