When cAP with double band with ac

Anybody knows if Mikrotik is going to launch new cAP/wAP with double band and AC networks.
If YES - When ?

We have not announced any such products yet. Maybe in near future, but I have no specific announcement right now

Now if you need it - the only way is build your own dualband AP.
