I'll take life - sentient or otherwise. Just imagine what an impact such a discovery would have on biology if it was not based on DNA!
If non-terrestrial life is informed and described by DNA, then that also is exciting, implying as it does that DNA is sufficient for life to arise on independent worlds.
I can only hope that I'll live long enough to be around when "it" happens. 
Perhaps 2012 will be the year.
