Really? They've been trying to phase out usage of 16-bit code since Windows 95 - 10 years ago. And even with this push, it'll still be the successor to Windows Vista that will be entirely 64bit (Vista will still come with a 32bit version, that will run 16bit apps to the best of my knowledge). yes, vista runs 16-bit code. i'm using windows vista right now, actually. full support for command line and 16-bit applications.
