What "standard theory" of galaxy formation did you have in mind? Why
would you expect all massive galaxies to form early? It seems much
more natural to expect a range of formation times.

Maybe this will help

By the way, the distances given in the press release correspond to
redshift 0.2 or so. That is more or less "now" as far as the history
of the Universe goes, but it isn't nearby on the scale of the Local
Group or Virgo Cluster or even the Coma cluster (z \approx 0.02). If
you have to look that far away to see the nearest of these objects,
they must be rare indeed.
