Amazon has just sent out press invites to a media event being held in California on September 6th. While there is precious little detail to go on, the new Kindle Fire has been heavily rumored to be launching in Q3 of this year. According to an AllThingsD source from July, the new Kindle Fire will have WXGA (1280 x 800) display, just like the Nexus 7, and will be thinner and lighter than the current model as well. Other than that, well, we'll just have to wait until the 6th.
