Onkyo tablet roadmap shows a selection of Android and Windows devices in a variety of sizes

Onkyo is giving us a taste of what next, revealing its plans for future tablet onslaught that will leave no operating system untouched -- well, Android and Windows anyway. For Windows 7 lovers, the company's three SlatePC tablets, the TW317A5, TW217A5, and TW117A4 are all going to see updates through the year, including Oak Trail power from Intel sometime before June. Meanwhile, the 10-inch Android SlatePad TA117C1 and TA117C3 will receive built-in 3G and will be joined with a 7-inch, ARM-powered model later this year. Ruggedized tablets are mentioned too, but no plans for a US release for any of them. No surprise there.
