Before we get started, let's clarify something: this information is probably not relevant to you, unless you work for a major game publisher. Today, Ouya announced that they have some more Dev Kits available for pre-order if you want to get early access to the Android-based gaming console. The price tag (and this is why it's not relevant for you) is sitting way up there at $800.
For the cash, those purchasing the Dev Kit will receive one console, two controllers, and the OUYA Developer Kit. The Developer Kit, which is a separate entity from the Dev Kit, is an SDK (or ODK as they call it) that can be used to build and test games on the pre-release hardware.
