I have seen rumors with and without A/C all over the internet. Until Disney themselves says yes or no its all a rumor.

There are a few methods to achieve A/C on Gondola's. Most common is to use capacitors. These are similar to batteries but charge extremely fast while the gondola passes thru each station. They can also provide large amounts of power rapidly to power the A/C. They do not need to last more than the time from one station to another. London has such a Gondola across the Thames.
Doppelmayr is the manufacturer of the Gondola to Sentosa in Singapore, which has equally hot and humid summers. They recently upgraded that 30 year old system to increase the capacity, but to my knowledge did not add AC. If that gondola is fine without AC I think we will be too.
Air conditioning requires a huge amount of power in Florida's heat, something that batteries/capacitors cannot provide. The London gondola system does have AC, but people say they can't tell the difference. And London's summer is as hot as Orlando's winter, which is how they can get away with using capacitors to power their ACs.
You are right to say that we are just babbling when whatever will be will be, no matter what people say. But to be mentally prepared, it is more reasonable to assume that there will be no air conditioning.
And speaking of the Asian countries...I was in Hong Kong once when our airplane arrived but couldn't go to the gate, so we had to get out and get on a bus and be driven to the gate. The bus had no air conditioning, and the ride was very short, less than five minutes. Within that time, I was soaked in sweat. But other than that, I was fine, didn't die or anything.
The Asians are fine with no A/C, but we are Americans spending a boatload of money going to Disney World, and we are used to air conditioning everywhere. Are we as fine as the Asians?
I believe people will withstand the heat if they can be buzzed over to Epcot within 10 minutes, no wait time. That's even faster than the taxis. That's worth getting sweaty for. We will just develop a new saying: When you see a sweaty family, you say, "Just got off the Skyliner?"
I won't take it, though. At first I thought I would, but the more I think about it, that's such a sucky way of getting to Epcot! Disney World is turning into a third world country? Ew! I'm getting the Minnievan, goodness.
Given the choice, I will still take the bus. The bus is one reason I prefer Disney World over
Disneyland. That blast of air conditioning cannot be beat!
