I think the current system at PG Music works just fine. They aren't locked into issuing an upgraded version around this time each year, although they have for several releases done so. To complain about buying a set or two of RealTracks a month or so ago now that the new versions are out isn't justified, in my humble opinion. I've bought sets of RTs as well, and then jumped up and down when I found out I could get them ALL for a bunch cheaper at some later time. With 82 sets out now (and growing no doubt), upgrading is still a very good deal. So you paid more than if you had waited. You wouldn't have had access to the RTs you did buy. You can play the what if game until the cows come home and never buy anything if that is what you want to do. You just won't have anything.
Good job PG Music. Keep up the good work, and don't try fixing your system until it is broken. It is working just fine.
