Here’s a little additional fodder for the iPad 2 rumor mill. Japanese blog Macotakara has posted a nearly three-minute video showcasing what are — purportedly — third-party cases for Apple’s second generation iPad. Previously, the same blog leaked images of what they were claiming was the exterior casing of the new device. The iPad 2 is expected to launch sometime in 2011 with the exact release date ranging anywhere from February to July — depending on which analyst’s opinion you fancy. Hit the jump to check out the aforementioned video.
