If we get an ocean pack, I don't see swimming in already released worlds have swimable oceans. That would mean a brand new WC and OS, etc. and they aren't going to remake all the worlds. IMO

Well your right. The worlds we have now won't have swimmable oceans but I would hope a vacation destination would or it will be a major disappointment to a lot of people.
