Microsoft's Surface tablet goes on sale on October 26, but the company is already working on the second generation, reports TechRadar.

The news comes from job postings on the Microsoft Careers site between June and August.

According to the postings, the Surface 2 will be the latest in Microsoft's "new family of PCs built to be the ultimate stage for Windows."

For example, a posting for a mechanical engineer position seeks out someone with an "understanding of touch display architecture and experience in mechanical integration of large touch displays into electronics products," so TechnoBuffalo speculates that the Surface team is also working a successor to the 80" Perceptive Pixel wall screen.

It's not a huge surprise that Microsoft is hard at work on its next-generation tablet, but the news does show the company is getting serious about hardware.
