Hooray! It'll be a big step forward for science if we get to know more about Dark Matter and discover the Higgs Boson. However, the benefit of this knowledge is not likely to result in anything palpable for another generation or two. It's truly a gift from our times to our children's children, much like most fundamental research.
The Hubble Space Telescope is a good example - amazing images of the Universe - we've learned so much about its evolution and scale. Hubble also discovered Black Holes, an unforeseen bonus. Perhaps in a few millenia we'll be sailing the Cosmos as a result of it, but for now, it's just a peek at a great mystery.

It´ll be some time still until they do the real tests with it - the collision of 300 billion atoms (or electrons or protons?) at 99,99999...% speed of light at minus twohundredseventysomething degrees C. I read a long article in Germany´s best newspaper "Die Zeit" last weekend about it. They said it´ll create a temperature 100.000 times higher than the sun - but forgot to ask what this means for the LHC.

It'll never work.
Since switching it on will destroy the Universe, in our parallel universe we will have survived because bizarre, low probability accidents will prevent it from being switched on (as per Quantum Theory).
This theory is being circulated by some distinguished theoretical physicists, as per The Telegraph:
It seems ridiculous to me as well, but one point to keep in mind is that quantum physics can, in a sense, be thought of at two levels -- mechanics and interpretation.
The mechanics consist of all of the various experiments and the theories that describe their outcome. It's very sophisticated mathematically -- the complete system is referred to as the "Standard Model" and makes very accurate characterizations. The only major missing piece is the Higgs field and its boson(s).
The "problem" is that is nondeterministic, it is statistical -- not due to lack of information, but quite literally all outcomes are possible until one is "observed." This has caused some great physicist (for example Einstein) to reject the whole system. He once quipped that God does not play dice.
Most physicist find it impossible to reject it, so they look for an "interpretation" to restore some determinism. The largest group ascribes to the minimalist Copenhagen interpretation (Neils Bohr) which simply states that the act of observation causes a definite state to arise. There are blocks of physicist who can't accept that and look for alternate "interpretations". Many-words, many-minds, consistent-histories, multiverse, are just some of the many interpretation's that are the subjects of spirited debate and dozens of books.
Physicists all believe in the same set of mechanics so they can share experiments and build things like the LHC, but -- in their minds favor different interpretations. I'm sure these particular physicists understand the mechanics and yet firmly believe in their particular interpretation that gives rise to this very strange prediction.
Trouble is, neither Quantum Mech nor even Probability Theory are concepts that are experientally understandable. We keep trying to explain complex mathematical theories in easy to understand terms, but our poor brains are not wired for that. Feynman and Sagan got that; Hawking and Greene did not. Trampolines to explain space-time distortion? Bah!!
What will be the next episode for the LHC?
It looks like the Big Machine has definitetly got some karma there... Wow!
I think the next steps are just a gradual series of steps to the LHC becoming operational by this month end at low energies. It will be shut down again later in 2010 and then it will go full blast at 7 TeV. And even then, the petabytes of data produced will take many years to process.
The race is on between the LHC and the Tevatron in the search for the Higgs Boson - whoever is first, Mankind is still the winner.

Quoting Comorin (Reply 22): The race is on between the LHC and the Tevatron in the search for the Higgs Boson
There've been intermittent rumors for the last year or so that it was found at the Tevatron. The Higgs might well be within the available energy range of the Tevatron, but even if it is, the LHC has much greater beam intensity (more collisions), so the odds favor the LHC as time goes on.
Even if the LHC should lose that race, there are still big fish to fry -- like looking for signs of super symmetry --- most string theories require it, so finding it might be a good sign.
