I did notice a few styles on the S900 with 16 bar loops..."Modern Jazz" and "Bebop" which has a 32 bar loop(very cool!) on variation "D"...along with quite a few that have at least 8 bars...so they are at least thinking getting more into it.

Most of my own custom styles are over at least 8 or 16 bars...gives them a more realistic feel(less repetition).
