they always have been very consistent these past years with .5 and primary releases in the october - December window. I thought i’d stop upgrading for a while with cubase 8 but they always managed to sneak in a few features that I really wanted cubase to have, not to mention the performance improvements I had since 9. Where I have like 1/3d increase in performance headroom for the tracks that I made on this 10 year old pc. The streamlining of the interface itself in 10 was also a good move.
If you check the historical release dates from version 7 in 2012 and forward at the bottom of this article, you’ll have a very good hint on when to expect the release… (mid-November last 2 years, early December the 5 five years before that). It c-o-u-l-d change, but I doubt that. https://en.wikipedia.org/wiki/Steinberg_Cubase
