Mysterious 10-inch BlackBerry PlayBook appears in Vietnam

The last we heard, all notions of a 10-inch PlayBook had been shelved, with rumors suggesting that RIM wanted to concentrate on its BB10 plans and next-gen smartphones instead. However, we've just received these images from Tinthe, showing off something that looks very much like the bigger BlackBerry slab.

A handful of photos, comparing the tablet to the existing 7-incher and an iPad, were sent in by forum member quang3g, who appears to be involved in BlackBerry sales.

 Looks-wise, the hardware's largely unchanged, aside from the bigger footprint and a screen ratio that appears closer to the iPad competition, rather than the widescreen shape that arrived on RIM's first tablet.

According to the brief teardown shot, there's a potent 7,250 mAh battery housed in the still-slim 10-inch frame, while it's worth noting that the tablet also includes a SIM holder and cellular radio -- though there's not enough meat here to discern whether it deals in 4G or 3G (HSPA+) radio waves.

While we wait for the official word on the existence (or cancellation) of this flavor of PlayBook, you can take a skeptical sideways glance at several more pictures of the tablet at the source below.
