It has been speculated for long that Research in Motion (RIM) would be launching a 10-inch version of its PlayBook tablet. But so far, there has been so concrete evidence about the same being in the works.

Now a Vietnamese website Tinhte, has posted pictures of a 10-inch BlackBerry PlayBook and also indicated that this tablet can be a reality very soon. This tablet looks much like the 7-inch PlayBook that is already in the market. From the posted pictures it appears that the 10-incher BlackBerry PlayBook will come with a 26.82WHr battery and will also have a SIM card slot probably to support 4G LTE network.

It is noteworthy that the 4G LTE version of 7-inch BlackBerry PlayBook was expected to be available in Canadian markets soon through telecom service operator Bell.

As far as specs for this tablet are concerned, it will have a display resolution of 1024 x 600p and a 4800 mAh battery. Powered by 1.5GHz dual-core processor, LTE Playbook will have 1GB RAM, and runs on OS 2.0. There is a 5MP rear camera that can shoot full 1080p HD videos and a 3MP front-facing camera as well.

The original BlackBerry PlayBooks came in three variants of 16GB, 32GB and 64 GB but it is being speculated that the LTE version will come only in a 32GB version.

Coming back to the 10-inch tablet, it was earlier being touted that this device may see the light of day by Q3 2012. But now, with BlackBerry pushing back the launch of its much awaited BlackBerry 10 OS to 2013, the tablet might be pushed to a later date.

As of now, there are no further details available with regards to the specifications or expected pricing for the 10-inch BlackBerry PlayBook. However, this tablet will be a crucial part of BlackBerry's future portfolio as it attempts to make a comeback in the smartphone and tablet market.
