Tech enthusiasts may have reason to rejoice as Amazon.com has sold out of its Kindle Fire Tablet. While seemingly bad news, this lack of product may signal that a new model of kindle is on the way. Often times when a tech device becomes sold-out, it implies that production on it has ceased in anticipation of a new model, as could be the case with the kindle.Adding further credence to this theory is the Washington Post’s report that Amazon has a press conference scheduled for next week, where it could possibly unveil an updated Kindle Fire tablet.The Kindle Fire Tablet is a part of Amazon’s kindle line of e-readers, capable of storing not just books, but also other media like music and movies.
