The smarter Siri is clearly coming to the HomePod, but I would bet good money your current HomePod won’t be getting it, so hold off on buying one this month. This is the typical hardware+software upgrade route. “Amazing” new features are developed, but they will only run on the latest and greatest hardware.
I am guessing that I, like others, already have firmly established smart home setups tied to a particular provider. My primary one is Google Home, but I have Amazon and tiny bits of Samsung and Apple in the mix. Would I integrate the new HomePod into my environment? Absolutely. But only if someone provided it to me for free (wink wink), since I can’t upgrade my hardware every time a new feature comes out that is only supported on the new hardware.
But I am super curious to see what innovations will come with a “new” Siri tied to an “updated” HomePod.
