Google may have some competition if the rumors turn out to be true and it announces its own 7-inch tablet as CNET reports that the Kindle Fire could see a new successor as early as July 31. This would make sense to help Amazon combat Google’s rumored Nexus tablet. Some of the changes could include a new built-in camera which the previous Kindle Fire lacked, physical volume buttons to replace the current on-screen controls, and a higher resolution display. All of these things would fit right in in a tablet that would follow-up the hottest tablet besides the iPad. Unfortunately, there’s no word on whether or not this latest tablet from Amazon will feature Gingerbread or Ice Cream Sandwich as it’s core software. We’ll have to keep our ears to the ground for any more news regarding this latest development on the Kindle Fire. Be sure to watch the site for any updates!
