iPad 2 sports A5 processor, 512 MB of RAM, cameras, thinner design? Apple to talk iOS 5 and cloud on March 2?

Engadget has retracted its earlier report claiming that Apple’s second generation iPad will include an SD card reader and a “super-high resolution” display, and is now backing up much of what we have heard about the iPad 2 already. Engadget‘s sources claim that the new iPad will feature the same display as the first generation model (screen size and resolution) and will be mostly a tech spec update. The new specs are said to include a brand-new, faster processor called the A5 in addition to a RAM upgrade to match the 512 MB found in Apple’s flagship smartphone (iPhone 4).

Engadget is also backing up the reports that the new iPad will rock cameras. Engadget does not seem too sure about the back camera, and seems to be going off the of purported physical mockups of the device, but they are certain about the front-facing camera for FaceTime calling and such. Engadget also touches upon the mystery behind the iPad 2’s unknown port found on our very own iPad 2 case at 9to5mac HQ and on our exclusive iPad 2 mold drawings from a few months back. They are not too sure about the purpose of this new port, or if it will even come in the final hardware, but it may have something to do with some last-minute engineering shifts.

On a final note, the report presents some hints at what else we might be seeing on March 2nd at the Yerba Buena Center in San Fransisco. They think we’ll be seeing a preview of iOS 5, which makes sense since Apple usually holds iOS developer previews in March/April, in addition to some talk about Apple and the cloud. The cloud point is still very vague at this time.
