It will not open until they are fully satisfied that it is safe and fully ready to do so. Clearly they do not feel that it is at this stage yet. I'm sure they want it open just as badly as we all do but they have a responsibility to ensure that they've done everything that they can to improve the safety of the ride. I'm sure they know far more about what they are doing with their ride in their theme park than you do.
They will want it open as soon as is ready, that point of 'ready' is not necisserily a fixed point in time.
