Rumors have been circulating for months about the next-generation iPad. Now they’re really ramping up. Wednesday saw the release of its supposed specs, and when it could arrive.

Boy Genius Report claimed a source had an iPad 3 prototype, and sent the tech site various development images that reveal more information about the device and its components.

Meanwhile, Amazon added two iPad 3 books to its European site — Ipad 3 pour les nuls, or iPad 3 for Dummies in French, and Auf die Schnelle iPad 3, which is German for iPad 3 on the Fly, according to a report from GameZone.com. iPad 3 for Dummies is scheduled to be published on March 29.

As for the specs, the images obtained by BGR show data points to model numbers J1 and J2, which refers to “iPad3,1″ and “iPad3,2.” This indicates that the iPad could be made available in two different versions — one for Wi-Fi and one perhaps with Wi-Fi and GSM/CDMA/LTE.

“From the data in the photos, which contain the output from an iPad 3 using a development and debug tool called iBoot, we can infer plenty of information about the upcoming iPad 3,” BGR said.
