Yes, that's what they said for Opera 16, too, and 15. Last version of Opera to be released for Linux was the (pre-blink) 12.
I'm sure they will get around to it eventually, but I've personally given up waiting and switched to Firefox (mourning the loss of my beloved spatial navigation, which was why I'd stayed with Opera until now). (Being able to access all my bookmarks from Firefox for Android is a nice side-effect, AFAIK Opera still haven't gotten around to implementing Opera Link for Android version).
(On a more practical note, for why I switched to FF - the latest Presto may not be much more than a year old, but you'd be surprised how fast the web changes when you're using an unmaintained rendering engine. New website functionality often doesn't work - html5 file uploading on most sites is broken, can't get the new google maps, g+ and fb are slow, etc. Web devs don't test on presto now that opera for windows/mac doesn't use it, and opera have stopped packaging website shims).
(Note also that there had been large delays in Presto reaching Desktop before — most notably with Opera 10 (2.2.115) and 10.10 (identical but with Unite enabled), Mobile shipped a beta of Mobile 10 with Presto 2.3.something before 10.10's release, and a second beta with 2.4.15 shortly after. Note from late 2.3 Presto releases, the final digit is the most significant one.)
