Looks like the Windows 8.1 update is going to be bigger than expected. A Reddit user has revealed certain features derived from their SDK. What's coming? A Siri-like digital assistant named Cortana, a souped up Action Center for notifications, possibly the ability to install apps on SD cards and improved system-wide SMS handling. Looks like Windows Phone 8.1 will be getting better, I wonder if there will be new hardware to showcase the new features.
