"The next version of our operating system, Windows 8, will be generally available on October 26, 2012. At that time, we will begin selling the Surface, a series of Microsoft-designed and manufactured hardware devices," said Microsoft in its annual report, which was recently filed with the U.S. Securities and Exchange Commission.
Microsoft announced its Surface tablets at an event in Hollywood last month. The tablets will be available in two versions; the ARM-powered Surface will offer 32GB or 64GB of memory, while the Surface Pro is more geared up for business folk, promising Intel's Ivy Bridge processor and 128GB of memory.
Official prices for both slates have not yet been set, although Microsoft did use the SEC report to vaguely suggest the tablets could start anywhere from $500 and go up $900.
"Suggested retail pricing will be announced closer to availability and is expected to be competitive with a comparable ARM tablet or Intel Ultrabook-class PC," said the Redmond firm.
Towards the end of last week, Microsoft admitted that it may have annoyed some of its Windows 8 tablet vendors by launching the Surface tablets.
