In all seriousness, I think they are waiting to see how the Gondolas work use the excuse that the Monorails have become a safety issue along with being financially hindering and just stop the Monorail program altogether and take out the trains and the tracks, alter the monorail stations to accept Gondolas and that problem will be solved. They may have to take the heat for a while, but, if the Gondola's work, like I think they will it will just be a few grumblings from old timers and before long forgotten. People will still go to WDW, it just will be different then before. It already is way different then it was when I first went there in the early 80s, but, in spite of losing a lot of things that I thought were great back then... I still have continued to go. Sure the Monorails are iconic, but, so was TGMR, 20K, Horizon, Imagination, they are all either gone or made mediocre, but, people still show up and pay mega-bucks to be there.
The problem right now is people need to stop overreacting to every incident that happens before it becomes a self fulfilling prophecy. Every time a small incident/accident happens the sky is falling scream is just speeding along that decision. I understand the Disney has billions in profit so we all think it unreasonable that they haven't bought new ones yet. However, that same financial worth of the company is a huge incentive to make sure that they are safe. They have deep pockets and a negligence lawsuit can drain a whole lot of those dollars down pretty fast. So far, in spite of a few minor problems and one major accident that didn't involve any guests, it has been a pretty spotless record over the last 47 years. Also we need to keep in mind that there were probably a number of things that happened that we don't know about before social media provided instant and very seldom accurate immediate reaction.
