I think the most important message here is that they haven't abandoned the arranger market completely, which was to be feared after the dissolution of Roland Europe.
But with Roland Europe's demise, I think the BK line has been given up, so they are obviously taking up the former "E" line again.
As Bachus said, one of the target groups in geographical terms might be the Turkish/middle east/Asian market, but I guess it will be marketed quite evenly worldwide. With the WAV sample expandibility, I guess it is not primarily focused on the older age groups.
