Sony's next-generation tablet appears to have leaked on internal slides spotted by German news site, Mobiflip. In short, it's thinner and lighter than the Tablet S, while internal specifications also trump it, including a Tegra 3 quad-core processor, Android 4.0 ("or later"), 3G connectivity and three storage options: 16, 32 and 64GB. The whole tablet follows the same folded magazine design of Sony's existing tablet, is splashproof and houses a 6,000mAh battery that the slides suggest will manage 10 hours of WiFi-based web browsing. There's even some tentative pricing, with the different-sized models marked up at $450, $550 and $650, respectively. The pictures also cover Sony's plans to add a lightweight keyboard to its next tablet, similar to Microsoft's Surface plans, but with some Smart Cover-esque kickstand skills thrown in for good measure. We've added a shot of the keyboard cover after the break, but you can take a tour of the rest of the slides -- which include a raft of accessories and docks -- at the source link below.
Update: We've been in touch with a Sony spokesperson, who had "no comment at this stage." We may have to wait until next month, when European trade show IFA kicks off -- with Sony in attendance -- until we hear anything more concrete.
