The 2010 Lindau meeting took place in the Bavarian town from June 27th through July 2nd. See the
John Timmer just wrote an article for Ars Technica - which I actually consider the best semi-mainstream source of science news on this planet - about SUSY and Gross's talk.
Timmer uses John Ellis as the main source of technical details. Ellis believes that 1 trillion collisions (1% or 2% of an inverse femtobarn) could be enough to see SUSY. That could come by autumn 2010; so far, they have 2x 36 billion or so. Rolf Heuer is comparably optimistic in an interview with BBC, stating that SUSY would likely be found by the LHC before the 2012 shutdown.
Of course, the main arguments for SUSY that Gross mentions remain dark matter, gauge coupling unification, and the hierarchy problem.
If you feel some deja vu, we discussed the Lindau Meeting of 2008 where 50% of the Nobel participants were AGW skeptics.
