When Sony announced it will organize a special “unveiling event” in Berlin at the end of August, we knew that the company was preparing to launch at least a couple of new and exciting products. However, it will be hard for the Japanese to surprise us in any way, as their future devices have been almost certainly revealed.

The Hayabusa phone has been known for a while to be the global version of the already unveiled Xperia GX, the Mint has leaked not long ago, and now an “Xperia Tablet” has been revealed online. The leak seems very trustworthy, not due to its source, but due to the information revealed, which is clearly too elaborate to be false. There are no less than 17 presentation slides mentioning the tab, and we couldn’t possibly understand why someone would go to the trouble of fabricating so many photos.

According to the slides, the slate will be an evolved version of Sony’s Tablet S, keeping its design guidelines while upping the ante in terms of hardware and software.

Powered by a quad-core NVIDIA Tegra 3 processor, the new tab, whose final name is unknown, will be sporting a 9.4-inch display with 1280 x 800 pixels resolution. Among the future device’s technical highlights, there are dual 8 MP/1 MP cameras, a 6,000 mAh battery supposedly capable of running for 10 hours on a single charge, 3G, Bluetooth 3.0 and WiFi connectivity. The new tab will come in three versions, with 16, 32 and 64 GB of internal memory, all set to come with SD cards, ST ports, HDMI, and DLNA.

Sony’s upcoming tablet will run “ICS or later”, according to one of the leaked slides, which give us hope that it might actually come directly with Jelly Bean. What’s clear about the gadget’s software, however, is that it will include a few Sony-exclusive tweaks, the most intriguing one being by far the “Guest Mode”. That particular function will allow users to set preferences for the tablet’s owner and for guests, which would come in handy if, say, your parents like to borrow your gadget from time to time, but they only need access to a couple of apps (or you only want to give them access to a limited number of apps).

The Xperia Tablet will be PlayStation Certified, and will also be significantly thinner and lighter than the S, while still having that original folded magazine look and a splash-proof body. Almost unbelievable, today’s leak reveals all there is to know about the upcoming tab, including what kind of optional accessories Sony will release alongside it, but also the 9-incher’s “suggested retail pricing”.

$449.99 could be the 16 GB model’s price tag, while the 32 and 64 GB versions will add $100 and $200 to that pricing point. It’s true that you won’t find the tab’s release date anywhere in those photos, but the leak’s source tells us that it should be put up for sale sometime in September. That means that, almost certainly, Sony will be unveiling it in Berlin in less than a month. Anyone excited about the Xperia Tablet? Do you think Sony needs to work a bit on those suggested prices for the 9-incher to become successful? Or will you buy it no matter how much it’ll cost?
