Yep, scrubbed for today, although they were proceeding with the new tank version pressure test, which is setup on a stand at the pad. They have a new tank design using 3mm stainless, with internal load spreading bracing, which is hoped to achieve NASA crewed space flight pressure targets, while also reducing the overall weight to boost payload capacity of the vehicle. They pump liquid nitrogen into the tank first to "cure" the structure, apparently these stainless tanks become stronger when treated cryogenically, then after a couple of cold soaks, they push up the pressure, to the point of failure.

Update: Elon has Tweeted that the Pressure Test was successful.
