The actual tweet itself..
...giving my thoughts whether or not it should/will happen, I'll say this.
1.) It gets rid of a screen-based attraction based off a dated IP. Sure, T2 is one of the most iconic summer blockbuster films, but it's not something that the park can rely on to attract a large crowd. TWD, can do that. It's a popular (ish) IP that much like Simpsons, attracts an adult crowd.
2.) It'd be a practical attraction with live actors, animatronics and special effects. It's something that would help alleviate the screenz issue that the park (especially for USF) has been having throughout the past few years. It'd also allow them to change the maze at specific times through the year to make it more intense, which can be a plus side for locals and would potentially due to the space of the T2 building, allow for more show scenes off of future seasons to come; allowing the die hard fans and locals something new every once and a while.
3.) It's a IP that can get a crap load of money. At the end of the day, money talks; and I think no matter what, it makes sense to get it there full time as opposed to just specific times throughout the year.
Will/could fans of T23D be upset? Yes, but it's a reasonable trade for something that is practical and not exactly something at UOR (not as a full attraction..and not as pop out actors).
