Maybe the 750 Gev resonance will soon prove not to be real, but with accelerators upping the energy into new areas there is in my opinion almost certainly new physics out there, whether it be 750 or 1800 or whatever.
I don't see why there is negativity about the chance of new physics though IMO is will not necessarily be explained by SUSY.
