The Zvezda Hobby vk.com page has the Zvezda 2017 catalog pdf (Russian) for download in the documents section:

There are only two new 1/72 Art of Tactic sets listed, both are the HQ units that were previously only included in the Battle of Moscow box game 6261. You can see pics of both units on this page (both the German and Soviet units have scissor binoculars)

The two new sets are numbered 6231 (Soviet) and 6232 (German).
So same pattern as 2016, two 1/72 small sets that were previously exclusive to a box game. Not surprising at all but disappointing all the same.
The Art of Tactic Kursk box game (6233) that appeared in the 2016 catalog (but remains unreleased) is listed again and there's a new box game (6235), I can't read Russian but based on the picture it is the Battle of Berlin. The most recent 1/100 kits are late war, I'm guessing they will be included in the latter set. I'm hoping there might be some new exclusive 1/72 figures in either box game that we might see sold separately in another year but not likely.
