The next big reusability step is to, er, actually re-use something!
I'm not interested in any SpaceX test flights with a re-used booster, there needs to be a paying customer. Also the payload must be put into the intended orbit by SpaceX. However, it doesn't matter whether or not the re-used booster is again recovered.
Having to keep the poll open only for a little while in case SpaceX makes any announcement soon.
