iPad 2 to Be Smaller Via Thinner Bezel, Maintains Screen Size: Report
The report states that the screen size of the iPad 2 will remain the same, which is logical since Steve Jobs famously said that 10 inches is the minimum effective size for a tablet's screen. Despite that, by reducing the size of the bezel around the screen, the iPad 2 will be smaller measuring 239mm by 186mm. The current iPad measures 242.8 mm by 189.7 mm, and was criticized for its wide bezel when it was first unveiled.

Speaking of moving, the speaker will move, as well, according to MacOtakara. Moving it from the side of the iPad to the back could be done to prevent someone holding the device from blocking the speaker holes. The new speaker will be wide range, the site claimed, offering better distributed audio at off-angle viewing.
The site said that front-and-rear facing cameras were a possibility, not a sure thing. Most assume that at least a front-facing camera for FaceTime support will be added. Finally, the site said that shipments from factories will begin in January, which fits in with most rumors to this point.
