Since SCJP is a pre-requisite for other Sun certification exams, and hopefully it would be possible for some of us to take them as time and money permits, I'd go ahead with SCJP 6 and try to study for another exam.
I think SCJP6 certification would still be valid for the higher exams even when newer versions of Java are released (but you may want to verify this)
If you are not planning to take other Sun exams, then it might just be better to invest in reading material for SCJP 7 and then take it. Sometimes exam objectives change significantly or not much at all - some things may be dropped from older versions and some new things may be added.
Also, during job interviews, they usually tend to ask question from older SCJPs even dating back to 1.4 or 1.3 - so it wouldn't hurt to study the older versions too.
