Amazon debuted a more sophisticated version of Alexa on Wednesday that’s more conversational and can handle tasks on your behalf. But in a surprising departure from its usual playbook, the company didn’t announce new Echo devices to go with its revamped digital helper.

Alexa Plus is here but it's only supported by four Echo products as of now, and won't be supported by more than half a dozen Echo devices.

The new Alexa+ is getting good press so far, but it's not clear whether consumers will find it compelling enough.
