Imagine coming up with a model for running that predicts a 3 second 100m time. You know that's unreasonable, so you insert a bunch of "invisible" hurdles in the race that help to get the time back in the 10s range. You then set out to discover these invisible hurdles via some experiment. If you find them, your model is correct; if you don't you have to realize that your model is inherently wrong. Loosely, that's how a lot of high energy theory works.

So, a positive- or a non-result at the LHC could / will be a definitive road sign pointing the direction that particle physics will take over the next few decades. It will also provide a road-map for the next big accelerator experiment, the ILC (International Linear Collider):
