deprecated SUS in MCP 70-290 ?

I am prep for my first Microsft certification exam, 70-290. I need to learn this stuff to feel comfortable dealing with the MS 2003 Server which BES 4 is running on. For the past few months, I have been studing with Microsoft's own self-training kit for MCSE 2003. When I googled for 'SUS' to download, a MS link says SUS is deprecated late December. My question is, if I am going to take the test late December, should I study for the new Wuss instead of the SUS ?
