Shenzhen MacTop Electronics, a Chinese manufacturer, is now offering what it claims is a case for the second-generation iPad. Dubbed the “Crystal Case for iPad 2nd Generation,” the case appears to have different, slimmer contours than the first-generation model, with the speaker opening unusually large on the back, and a hole for a rear-facing camera in the upper left-hand corner, similar to its position on the iPhone and fourth-generation iPod touch. Apple has yet to announce or even acknowledge the existence of a second-generation iPad, although recent rumors have pegged the device’s release as coming within the next 100 days.

Update: Following our initial report, a second case was spotted sporting the same camera hole and expanded speaker-area cutout as the first case; the text accompanying the second image suggests the cutout is for a new SD card slot. The unusual size and shape of the cutout would suggest either the placement of the SD card above the current speaker, realignment of the speaker closer to the new iPad’s back with the card slot in its former place, or potentially a new pop-out door akin to the ports on the first-generation MacBook Air. All three possibilities seem somewhat unlikely in light of recent Apple design decisions.

Update 2: We’ve added an article briefly discussing how a rear iPad camera could work relative to other iOS devices and tablet competitors.
