I know people say this a lot, but I'm gonna say it.
The Bat is quite a walk from the rest of the park, which is a strike. From several accounts of riders it has a slow lift hill (which I'm pretty sure everyone is aware of) and its getting rougher, which is another strike.
But other than these factors, it would depend on The Bat's ridership and how much it takes to maintain it. If ridership is low and/or it become to expensive to maintain a ride, it would probably be in the parks interest to remove it. Parks have to make so much per acre, and if the park starts losing money, again, its in their best interests (business wise) to remove whats there and find an alternative to make better use of that specific land. But I do not know how much it costs to maintain The Bat or what it's ridership statistics are, so there are several known and unknown variables here.
