The way things have been going around 2nd amendment jurisprudence, it is impossible to know what might happen. Is IL going to come in and argue these are military weapons? If so that could lead to an even broader interpretation of the 2nd amendment because at the time of the founding, there were no restrictions preventing citizens from having the same arms that the military did.
Also if you read some of the comments below the video, Pritzker's comments after the SCOTUS ruling is that "we don't want automatic rifles in Illinois."
