Should Apple unveil its HDTV, this could result in US households doubling its spending on Apple devices to $888 (£560) on Apple devices by 2015. 

Apple's HDTV could be released with with a set of impressive features. Earlier this year, potential Apple HDTV buyers were polled to estimate how much they would be willing to pay for the device. A more recent survey revealed that almost half of iPhone users are already preparing to get their hands on Apple's TV set.

Currently, analysts are trying to figure out how much the average American household will spend on Apple devices after the long-rumoured Apple TV hits the shelves. Analyst Katy Huberty with Morgan Stanley, sees the US household spending in Apple products doubling with every significant product release.

In a note to investors, Huberty stated that US household spending doubled following the release of the original iPhone, from approximately $150 (£95) to $295 (£186.50) on Apple's products.

"Given a 97% TV household penetration and a 61% broadband household penetration in the US along with an expected high price (and value) point, an Apple TV is likely to generate a similar increase in average household spend, with some help from iPad and iPhone growth," Huberty said.
