First up, apologies for asking the same old question again. After trolling through the posts on here, I could gather that there is no word yet from Sun regarding this. I couldn't find anything on Sun's website too. I wanted to give SCJP 5.0, but the lack of 'hard copy' exam-oriented material is throwing my schedule slightly out of gear. So I was thinking of giving SCJP 1.4, and then the SCWCD which is more within my line of work. Also, we've yet to migrate to Java 5.0 at work, we still use 1.4.
There's nothing wrong with asking an 'old' question again, as long as you've done your due dilligence and looked to see if it was asked before, which you seem to have done.
To answer the question - I don't think Sun is going to discontinue it. They've been putting version numbers on the certifications for a while now to make it clear what language version you've taken the exam for. Plus, a quick gander at their website shows they're still offering the 1.2 programmer exam, not just the 1.4 and 5.0, so my gut says they'll be offering the 1.4 exam for a while to come.
