Android Central has obtained two alleged product timelines for more than a dozen Dell tablets and smartphones scheduled to launch throughout 2011 and into the first quarter of 2012. The leak points to a mix of devices based on Android, Windows 7, and curiously enough, a Windows 8 tablet (codenamed "Peju") arriving in January 2012.
Up until now Microsoft hasn't given an official timeframe for the successor to Windows 7, but we've known for a while that they are targeting a 2012 release and a couple of early development milestones have already been seen in the wild. If the slides are legit I'd venture to guess that the January estimate is likely just a placeholder date, though, as it would give Microsoft little over two years to deliver what it has claimed will be their "riskiest product bet" yet.
Windows 7 took about three years to build and it was essentially an evolution of Vista. This time around the company is building two separate versions of Windows 8 for system-on-a-chip platforms from Intel and AMD on x86 architecture, as well as low power designs from the likes of Nvidia, Qualcomm, and Texas Instruments on ARM architecture.
Besides that interesting nugget the slides show a Dell tablet planned for April, dubbed "Gallo", which will be running Android 3.0 Honeycomb. Following it in June will be the "Rosemount," running Microsoft’s Windows 7 and featuring an HD display with a resolution of 1366 x 768. In October will come the Honeycomb-based “Sterling,” and what looks like an update to the Gallo with handwriting recognition.
