If there is any fork that would make waves even beyond the ones that have come before it, its SegWits and the expectation is really high. This is a fork that Coinbase is declaring support for even before launch while those one that have launched are still being subjected to reviews. This shows that the impression is going to be massive and I see it going above the roof with the benefit coming along with it. On whether to drop or not, I think that will be a personal decision afterall its going to be a free money if you are not interested in trading but if not, its going to be hard having to buy it all over again.
