on FFG spanish sight they flat out change both the tank and krennic and troopers to 2nd quarter now. not sure if anyone has gotten anything from ffg yet about this

The tank (& speeder) were already set for Q2 release so this looks like nothing more than a delay for Krennic & Troopers (which honestly could be nothing more than a few weeks delay since March ends Q1 and speculation was 3/21 release date).
