There are three different versions of the Kindle Fire HD. The 7-inch and 8.9-inch models will each have 16 GB of storage and cost $199 and $299, respectively.
There will also be a Kindle Fire HD with 4G LTE and 32 GB of storage that will cost $499. The 4G LTE model will also give you 250 MB of monthly data for $50 per year. (We imagine there will be pricing plans if you want to use more data than that).
All Kindle Fire HD tablets are available for pre-order today. The 7-inch model ships Sept. 14. The other two models ship November 20.
