The next step will probably be a space observatory looking at ultra-high energy cosmic rays. The luminosity won't be has high as the LHC's. But as I understand it the software at the LHC throws away a lot of data, and may be throwing out useful information too - because it 'doesn't fit.'

So looking at single interactions in detail might not be a bad thing.

Anyway, I still want an anti-gravity flying car before I die.

So there's always that.
