As I've watched the last four series of Microsoft certifications come (and some of them go), I've observed that it normally takes two years from the time a new certification becomes possible to achieve before most people start targeting that program as their primary choice. As far as Windows 2000 and 2003 are concerned, that makes Windows 2000 a safe bet until late 2004/early 2005.
Go ahead and get your Windows 2000 MCSE as soon as you can, then plan to take the two upgrade exams next year or the year after, as events compel you to upgrade your certification. That way, you can use study guides, Exam Crams, practice tests and all the other aftermarket information and tools available to help you get past the current generation of exams, and give us content developers time to build materials to equip you similarly to take and pass the 2003 exams.
