Amazon today announced that its Fire TV platform will be included in 4K TVs introduced later this year by Seiki, Element, and Westinghouse.

The televisions, which are expected to be available in the second quarter of this year, will also come with a remote that will be voice-activated with Amazon’s Alexa digital assistant.

Amazon’s entry into the television manufacturing business will likely escalate its war with Roku, which is already included in televisions from such companies as TCL, as well as separate Roku-branded streaming stick and set-tops.

Seiki, Westinghouse and Element this week will showcase the new 4K Smart TVs with Amazon Fire at the Consumer Electronics Show in Las Vegas.

The Amazon Fire-fueled TVs will come in four sizes: 43-inch, 50-inch, 55-inch and 65-inch. The companies said pricing details will be announced later.
