New Apple TV to Start at $149, Feature Universal Search With Siri
Universal search feature will reportedly be a "cornerstone" of the new Apple TV, allowing users to, for example, search for one movie across services like Netflix, Amazon Prime Video, and iTunes, among others. The ability to search for actors and directors will also be included in the search options, and won't limit users to just movie or television show titles.
Sources familiar with Apple’s plans say that a cornerstone of the the company’s new set-top box is a universal search feature that will enable searches across multiple streaming video services as well as Apple’s iTunes Store. Instead of searching the catalogs of multiple video services one-at-a-time for a particular movie, you’ll now be able to search all — or most of them — at once and then choose the service on which you’d like to watch it. You’ll also be able to search for actors and directors, and run other more targeted searches as well — all with Siri.The report also claims that the new Apple TV will "start" at a price point of $149, hinting that there could be more expensive models with perhaps the possibility of expanded storage capacities. The $149 retail price does line up with previous rumors that pegged the Apple TV of launching with either a $149 or $199 price tag. The company has been said to be keeping the third-generation Apple TV, currently priced at $69, as an entry-level option.
Along with Siri integration, the next-generation Apple TV is rumored to feature an A8 processor, a touch-pad remote, and an App Store with an SDK available for developers to create apps. The new box will be aimed at more than just video consumption, with recent rumors hinting that the newly designed remote control will include motion sensors to support "casual" gaming experiences.
Update 8:52 AM: According to a follow-up report by 9to5Mac, the new Apple TV's onboard storage will be in the 8–16 GB range, and the touchpad remote included with the box will be black rather than the silver seen on the current Apple TV remote.
