The folks over at the certification group at Microsoft are offering a free beta exam for the new 70-433. Remember that beta exams are numbered with a 71 and not a 70. This is a nice exam to get you started with the new SQL Server 2008.
Good luck on the exam. Remember that beta exams do count toward certifications but you have to wait until they decide what questions to use and what ones to throw away. The last two beta exams that I have taken earlier this year took over 12 weeks to get results back, but I did pass both of them.
