Worth it to get MCDST right now?

I've been thinking of getting the MCITP Enterprise Support Technician cert. The test consist of 70-620 and 70-622. Then I wanted to take the 70-621 to upgrade it to MCDST. At first this seemed like a good idea but I've heard about Windows 7 and am worried I'll get certified for Vista with the MCITP and then have to re-certify not too long after because of Windows 7.
What do you guys think? Do it or certify for Windows 7 when that comes out?

I would pursue the certification now, if you always wait for the next thing to come out to become certified then you will never ever be certified.
Personally I wouldn't worry about Windows 7 just yet. My gut feeling is there's not going to be a huge change there and there will likely be transition exams available if they decide to roll out a new Desktop Support qualification for it. Besides which having a generation or two back of legacy systems shows employers that you're keeping upto date with your knowledge and that you don't regard certification as a one time event.

70-271 + 70-272 = MCP & MCDST
70-621 = MCTS & MCITP:EST
70-290 + 70-291 = MCSA 2003
All in that order. You'll need to work on a different elective if you go for MCSE.
Bottom line is, where do you see yourself and what is your experience? If you want to be doing desktop support in the near future or are doing it, both certs should on your list.
