Depending in what you need to do; when I last tried, for a legacy system, to run under Wine it was flawless. So by the time it becomes impossible to install I would say Wine will be advanced enough to run all you need. All Windows stuff I need these days works perfectly under Wine. I work a lot with software from almost a decade ago and that mostly just works. Maybe at that time (few years) Wine will run on Windows as well (it has been a long term roadmap feature) to offer just this compatibility layer for old software support without having to install a Windows xp virtualbox.
