Other trends that are here and emerging:

Animotion
Designed to be in motion, as opposed to logos that are designed flat and then animated.

Wreaths
Lots of elements, sometimes so delicate that they would not have previously been considered to be part of a logo design, assembled into a patterned whole.

Rainbows
Possibly growing from the buzzword "inclusiveness," likely emerging from clients' greater tolerance for brighter colors, but definitely fed by RGB.

Dragons
Lots and lots of dragons.

Holes
Designers playing with the apparent surface of the paper, with designs appearing to disappear into or emerge from sinkholes or cuts.

Numbers
A numeral inserted into a word in place of a letter, ideally to further the meaning of a wordmark, with text messaging and IM-speak everywhere.

Big Benday
Hyper close-ups of benday dots that overlap and randomize.

Cartouches
Shapes that are bracketed in one way or another.
