Hm. If this is the case, if I were a businessman, sooner or later I'd 
completely disable all non-DH based SSL cipher suites in my product and 
sell it with saying that it's so secure (as this is the reason for using 
SSL in the first place) that even packet captures can't be decrypted from 
it. In other words, based on what you've just explained do you think that 
SSL decryption will be long supported functionality of Wireshark or will 
it diminish in the future?

I'm just thinking theoretically here.

All the best,
