This is a good question. I don't entirely know of Arrow's current financial status, but I do know that Arrow will only get paid for THIS 4th dimension. So, yes they will get paid, but if it isn't successful, what are the chancs that another park is going to buy one? It wouldn't kill Arrow to have X be a failure, but it certainly wouldn't help seeing that this is their first project for a couple of years. I do not think though that Arrow is in anyway throwing in the towel. They have a lot of new concepts out right now, I have heard of the 64 passenger super train, an LIM coaster, and the Arrowbatic. The Arrowbatic, I may say, looks like one of the greatest ideas. Small space, low price tag(I assume), and big thrills.
