By this point, it's fairly safe to assume, though as yet scientifically impossible to conclude, that pretty much EVERY star will have one or more (probably more) planetary bodies around it. The race IMO should shift to determining valid ways of finding actual Earth-size, atmostphere-bearing planets within a star's potential Goldilocks zone. We are discovering planets almost weekly now, through analysis of passive observation, which is great. I would love for a breakthrough to be made in detecting planets like ours, which then puts us a step closer to potentially habitable worlds.
The race used to be about finding out what's there; I think we should be looking to find places for humans to ultimately go to.
