Amazonís rumored Kindle Fire 9-inch model could be shipping by as soon as the middle of this year, according to All Things D. Pacific Crest Analyst Chad Bartley has raised his estimates on Kindle Fire shipments from 12.7 million to just under 15 million units based on this line of thought. In addition to a new 9-inch Kindle Fire, Bartleyís research also suggests that the first refresh of the original Kindle Fire will also be revised at the same time.
