DUDES! Don't expect black holes! If these were possible at the low low energy densities that puny humans can create, you can bet that Tevatron would already have a few unexplained bumps in its probability density curves.
Expect possibly one Higgs or more. Possibly. Additional phenomena are bonus! It would be nice to have something new beyond the Standard Model, some supersymmetric particle or something. Don't hold your breath.
"What is so exciting about the LHC is that it could open up a new area of technology. If i'm right in my thinking, If you can get the standard model to work then you have a roadmap to a way of interating with Higgs via an EM field, which is pretty exciting."
Err...absolutely not. The Standard Model works quite well currently though no-one knows why it is the way it is. It's just a mathematical framework for the known particles and it indeed predicts a "Higgs", but does such a thing really exist? Don't expect wonder engineering to come out of this.
Here is a nice presentation of the state of LHC from "Strings 2007":

And a interactive presentation from the Science Museum to "Hunt for the Higgs":

And now I'm back to playing Half-Life
