To follow up on my last post, it appears that the 230i and M240i are coming in July as originally expected:

The fact that this is a US press release would seem to confirm we should expect these models stateside for MY2017. Assuming that is true, it suggests that there is no publically available, accurate production schedule for MY2017 at this time.
Whether we'll finally get the 440i in July as well, and whether we will also see the 330i, 430i, 330i GT and 340i GT this year too are still unknowns.
