Yes, I am definitely interested first in "Kafka related changes" because it's the biggest impact I currently have when trying to "port" my topologies from 1.2.x to 2.x.
The other topics are also very tempting, I think I'll jump to the "Java port" one as soon it's published.. Storm 2.x's going to such a big change for us, i'm impatient to dig this!
