Although I don't really want this to happen because it may negatively affect BTC price, I almost hope BTC forks into two competing solutions. One with SegWit /Lightning and one as Bitcoin Unlimited or something along the lines of what Craig Wright is talking about. I simply have no idea what to believe anymore and I'm not sure anyone else know what the best solution is until we see them compete side by side for a number of years.
That won't be bitcoin anymore, only alts. In that case, bitcoin (any of the new ones) will lose it's benefit that it was the first and only crypto for a time. Now, the name 'bitcoin' is a guarantee for the largest and oldest and widely accepted crypto coin. We already have a lot of alts, so there's no need to create a new one. We also have an alt with SegWit implemented, so if anyone want to test it, it's there, it's possible. I don't know what is the future, but I would prefer not to fork into two coins, but it's only my point of view.
