Microsoft corporate VP PJ Hough confirmed that the temporarily-named Office 15 had just entered the Technical Preview phase in what could create concerns for Windows 8 tablets. The stage sees a small group of customers get early access in secret to offer feedback as Microsoft moves towards a beta and an eventual release. Hough couldn't address rumors and leaks, but he did promise that it would be the first time Microsoft would simultaneously update Office's web, cloud, and server apps on both desktop and mobile.
