Crunchgear broke the news earlier this week — Amazon is set to announce a new Kindle format tomorrow. But this new Kindle isn’t going to replace the Kindle 2. The new Kindle is larger than its cousin. Ideally, the large format will make it easier to read electronic newspapers and magazines.

Engadget snagged some covert photos of what appears to be a run-through of the presentation that will take place on Wednesday. The new Kindle, dubbed the Kindle DX according to Nilay Patel of Engadget, looks like a larger version of the old Kindle — black and white screen included. Patel says that the DX’s screen will measure 9.7 inches (about 24.6 centimeters). The earlier versions of the Kindle have a six-inch screen (15.2 centimeters). It will also have one other new feature: Patel says that the new Kindle will have a built-in PDF reader functionality.
