If you have already studied for SCDJWS 4 then go for it because SCDJWS 5 will take a little time to come (maybe in Feb-Mar). If you are comfortable then go for SCDJWS 4 , you can then learn extra things of SCDJWS 5.

There is definitely new material to learn, however it is going to be even more scattered than it was for the SCDJWS 1.4 (for quite some time). The real problem for the SCDJWS 5 is that RMH isn't going to be updated (the author has moved on to other things). This is a problem if you are new to web services. So its basically a huge stack of specifications, white papers, and standards that you have plow through.
