Consumers buying a new Xbox One will not be able to watch Sky TV content through the console until next summer, it has been revealed.
Despite Microsoft including Sky's NOW TV service on a list of apps set to launch before the end of spring, it will not arrive on the Xbox One until mid-2014.
"[We] look forward to the launch of NOW TV on Xbox One by summer next year," a Sky spokesperson stated.
"As a dedicated over-the-top service, we have prioritised the availability of NOW TV, to extend the reach of the service to the main [television]."
Sky also revealed it has no immediate plans to bring its Sky Go app to the Xbox One, despite its existing availability to Xbox 360 users.
The spokesperson said that, looking ahead, the firm "will consider any future opportunities for Sky Go", but no concrete plans are in place as yet.
This means Xbox One users may have to wait for access to Sky's live streaming service, which enables TV subscribers to access live content over the internet.
Meanwhile, Microsoft has revealed the Xbox One TV guide - commonly referred to as the Xbox One Guide - will not arrive in the UK before the end of 2013.
Terry Farrell, Senior Product Manager at Xbox, confirmed this feature will become available to British console users at some point in 2014.
Xbox One Guide displays TV listings and allows users to change channels and access content using voice commands.
It will be available to Xbox One customers in the US from launch day on November 22nd 2013, but UK users will have to wait for this level of functionality.
Mr Farrell explained that Microsoft is discussing the integration of this feature with a number of different electronic programme guide providers.
At the same time, it is conducting tests on various TV set-top boxes, he noted.
"We are choosing to partner with these folks and they are excited about the idea of integration," he stated.
"We're testing all the boxes. You can imagine how many there are in the UK."
