Industry analyst Michael Pachter believes the as yet unannounced device will be delayed due to "overwhelming demand", reports CVG.
"We have heard no word yet from Microsoft or Sony about their plans to launch new consoles, but both manufacturers are widely expected to launch consoles by year-end 2013, although we believe that Microsoft could delay a new console launch until spring of 2014 in order to accommodate what is certain to be overwhelming demand among hardcore gamers," revealed Pachter.
GameStop CEO Paul Raines appeared to support these claims, alleging to have heard interesting rumours about next year.
"I'm getting a lot of rumours that are very interesting about 2013," remarked Raines.
"We have not been expecting two more consoles in 2013. We're expecting Wii U this holiday, another one next year, and another one in '14.
"These rumours change every week, but we're hearing more about next year."
Pachter previously suggested that Grand Theft Auto 5 might launch this summer, and was vocal in his belief that the 3DS had turned a corner after initial slow sales.
More recently, he suggested that the Wii U would struggle at market.
The Wedbush Securities analyst believes that the Wii U's Gamepad will be a hindrance rather than a help, potentially affecting sales.
