Yea.. there are multiple threads (on this site alone) with iron-clad scientific proof that you will die the moment you set foot in one of those floating deathtraps.
You should not count on it. Disney has not changed their 'fall' message a bit yet and when planning you should assume fall does not include August. This sort of platform requires an enormous amount of testing, retesting and testing again before they put guests into the gondolas and they will not launch until absolutely all of that is done. And since none of us knows the details of the planned tests or their progress against the plan you should continue to assume they will not be there in August and if they are it's a fun bonus.
