Case status &last updated date

I tried to post a message several times but did not get through. I don't know why?

I submitted my NIW140 to Vermont center about two years ago. I found the last updated date changed to yeasterday. However, the description for the case status remains the same. Does anybody have the same experience? Does that mean the decision about my case will be made soon? Is that a good or bad sign?

Many thanks in advance!
