@sgtlmj,

We really cannot say whether or not a specific model will receive the feature since we just don't know. The goal for the feature is to add the feature to as many Deco models as possible. 

The version 4.6 was the first model of the S4 family to receive the update, and only received it last month. I would expect the firmware to appear in the next few weeks, however there is no knowing for sure. the rollout for this feature has been taking place over the last year, so it may still take a short while for it to appear.
