iPad 2 to feature FaceTime camera and SD card slot?

Its pretty much a given right now that the next gen iPad, coming out in Ferbruary next year, will have a front facing camera for FaceTime. It is, however less certain that it will have a rear facing camera. An SD card slot seems far-fetched really. An image from Shenzhen MacTop Electronics shows supposedly a case for the next gen iPad with both a hole for a rear facing camera and a gap for an SD card.

If this image is real then the iPad will definitely have a rear facing camera however the opening for the SD card could have other uses. Any ideas what they could be?
