hi guys,
i think its time to move forward to MS next generation certification since i think my MCSA 2K "no longer" valid

(still can be used with 2003 platform - but now is 200

which path do you think best to take - since my certs cant be upgraded :
MCTS Windows Server 2008 platform (there are 3 exams)
http://www.microsoft.com/learning/mcp/windowsserver/2008/default.mspx
or
MCITP : Enterprise Admin (5 exams)
http://www.microsoft.com/learning/mcp/mcitp/windowsserver/2008/enterprise/default.mspx
my catch :
- i dont think that i need get in depth with Windows Server platform anymore since now i'm considering all platform work.
- i think the network infrastructure basic are pretty much the same from time to time (except ipv6).
- in Windows 2008, i think it will be pretty much GUI & system re-orientation? since my longhorn trial system looks like a much different then those 2000 & 2003 servers?
your opinion please , and thank you
