I have tried to search but could not see any serious planning of sending a fly-by mission to Sedna. Does anyone have any info if the scientific community is planning such...?

In my opinion, Sedna would be very interesting target, far more interesting than any KBO etc. The fact that it spends most of the time outside heliopause under the influence of cosmic rays during aphelion could reveal some interesting results and also the reddish colour it has might be worth investigating. And good for us, at the moment it is approaching its closest point to Sun on its orbit, so mission to Sedna would not be such a big effort if done e.g. a'la NH with Jupiter gravity assist...? Maybe possible NH2 could be sent that direction.......?

Any comments, any info? Especially the fact that it is a body from outside the heliopause, could that add some interest towards it?

Jupiter can speed you up or get you off the ecliptic, but it's a tradeoff. I'd love to see a proposal that used Jupiter AND an ion drive to try to reach Sedna in under 20 years. Something that wouldn't fly by so fast as to be useless, of course.
