I just confirmed this. My understanding is that the lower price will be
only for Cakewalk user crossgrades, not any other DAW.
FWIW although PreSonus and Cakewalk were "competitors," software development in a tiny, demanding, and declining market is not easy. Both companies had (have) a lot of respect for each other. There's a "we're all in this together" mentality among the developers I know in this industry.
