Same story here. Upgraded to 16 in early May, was expecting free or discounted upgrade pricing when 17 shipped, as is customary in the industry. I'll try to keep using 16 for another year or maybe longer before upgrading. 49.99 won't break the bank, but this doesn't feel right. This is all the more offensive because I asked their support on Twitter--ironically called @ParallelsCares--about my upgrade option, but never received a reply. They have a great product which many of us need to make a living, but their business practices are not in line with what many users have come to expect.
