MicroSoft have PC gaming market dominance and are starting to improve in console market withX360. There is no need for MS to enter the portable market. The Zune failed and I do not believe they would bother with a portable console game device.
Games for Windows on PC and XBox 360 is all Microsoft need for now. The future X360 will be released with a new XBox.
