yeah i have read all that stuff before, still don't see it, many things are in the wording, like there would be a big difference between just 'changing the name of sonar' and sonars 'line' coming to and end, and a new product taking over. if they said that regardless, people who purchased sonar platinum lifetime updates will receive any future cakewalk flagship daw product free of charge and continuing updates for said products in perpetuity, well that would be different, but they aren't actually saying that. time will tell
and if memory serves me correct, i think mr anderton has even alluded to the fact that lifetime updates will come to an end at some point.
