Is anyone else surprised that in the age of "retina" displays, these only go up to 64px?

See "How long did they take to make?" comment below.

One of the tags says "vector" so they may be able to produce higher resolution files. That said, I think the @2x should be in there if people want to use these for mobile.

They are @2x up until 32px.
