All vehicle types are developed independently. But specifically in the cases of smaller nations, they have a much more finite pool of possible vehicles. So for example when they have patch with a lot of content, the patches immediately after will be much less so for that nation regardless of what type. Otherwise they wont have much to look forward to or go even longer periods without anything.
So the point here was, Italy had quite a lot last update, including ground forces whatever your opinions on them were. So this update, there should be lower expectations for them in general.
Of course as I said, they may have something(s) new in the fleet department to look forward too.
