Hi,
as far as I can see, this is all the information currently available:
Let’s guess when it will be officially announced 
Comeon, this is more a raffle than anything else. 
What is the prize for the winner(s)?
It's a trap...an insider might vote 
+ 2-3 years. 
For example almost nothing on sale from Mikrotik 5G hardware roadmap shown more than year ago.
Newsletter #132 has been published. There is no mention of cap be. No one voted for #132 anyway. It remains exciting.
Especially since the newsletter, like the software, also has no schedule released dates. Even if you had some guess on months/years... it be an inexact conversion to @normis newsletter calendar.
I really hope they have good 2.5gbit hardware and cAP be (probably just the Qualcom SoC of the hAP be? with thread/matter,too, at best) by mid of next year, and in a good state, of course. Need to setup my new home and don’t want to go Ubiquiti.
Newsletter #133 has been published. There is no mention of cap be. I am the only one who voted for #133 anyway. It remains exciting.

Newsletter #134 has been published. There is no mention of cap be. Sorry @Amm0 @Matta @tetyys
Would be nice to see something smaller than cAP ax, like cAP ac sized WiFi 7 device...
