"Purchase process research showed it's not a top buying consideration, and anecdotal information indicated that actual usage was not high. We decided to drop 3D support for 2017 in order to focus our efforts on new capabilities such as HDR, which has much more universal appeal." -- Tim Alessi, LG Director of New Product Development
According to this site, Panasonic only has a single 3D set in 2017 (not 16 as you claim): http://www.flatpanelshd.com/article.php?subaction=showfull&id=1488787065
