Yes, the 1/2 bar fill is still a Roland feature..... real handy for country tunes....

I guess it all boils down to having MORE variations and MORE fills, and just labeling them musically. I sure wish arranger manufacturers would concentrate on arranger specific features to improve, and spend less time trying to turn them into compromised 'do it all' features.

An arranger is first and foremost all about triggering styles, and the first place to make that better is to give us more of them with more variations and fills. A 'Guitar Mode' is all well and good, but I'd happily trade it for four more variations per style, and a 1/2 time button would make it less complicated on the front panel.....
