Would you be surprised to hear that Amazon is working on a front-lit E Ink Kindle to compete with the Nook Simple Touch with GlowLight? Well, you shouldn't be — we've heard before that the retailer was working up such a device — and now Reuters is offering up a few more details on the rumored e-reader. According to an anonymous source with "direct knowledge of the matter," Amazon will release the nighttime-friendly Kindle this July with identical or slightly increased pricing from the current models, in both 3G and Wi-Fi varieties. It's not clear if Amazon will go the Barnes & Noble route and add the lighting technology to its currently-available E Ink readers or introduce a new design entirely. In addition to the new E Ink model, the source says that Amazon will introduce a new tablet at a 8.9-inch screen size this holiday season, a sizable bump up from the Kindle Fire's current 7-inch form factor. For now these are all rumors, of course, and we'll let you know when Amazon does introduce some new models.
