Hmm... no need to model those Acolytes in Power Armor with Plasma rifles any more.
It looks like when fired on Supercharged (the new Gets Hot) the model is slain on the to-hit roll of a one. According to the leaked rules, the only time the word slain gets mentioned is after all saves have failed and wounds are reduced to zero and the model is removed.
Roll a Supercharged one with a Plasma Pistol = firing model is slain.
Roll a one with Plasma Gun or Plasma Incinerator on Supercharged = resolve all shots (due to Rapid Fire, presumably) and then you're slain.
No armor save, FNP equivalents or the like, just slain.
(assuming I'm interpreting it correctly, that is...)
Nice.
