Is Albertosaurinae a new taxon?

IIRC, _Tyrannosaurinae_ was earlier provisionally defined as a stem-based clade
with _Aublysodon_ as the external specifier (albeit with a suggestion that
_Alectrosaurus_ might prove a better choice). Sounds like it's been restricted
a bit here. Were any definitions given or will we have to wait for the Acta
Paleontologica Polonica paper?
