While Apple (AAPL) prepares to attack the affordable tablet market with a smaller, cheaper iPad, Research In Motion (RIMM) is taking the opposite approach. RIM has been toying with a 10-inch tablet for quite some time, and the project was reportedly sidelined last year as focused shifted to the struggling vendor’s next-generation BlackBerry 10 smartphones. Recent rumors suggest the larger PlayBook has been resurrected, however, and will debut some time next year. A user on Vietnamese forum Tinhte published purported images of the device and we have no reason to doubt their authenticity. Few details are found in the photographs beyond the fact that it looks like a larger version of RIM’s 7-inch slate, and we can also see a 7,250 mAh battery in one image. There is also “BlackBerry 4G PlayBook” branding on the bottom of the tablet, so it’s safe to assume it will at least ship with an HSPA+ radio.
