No, wait I know what it means. Northwestern has decided that in light of THIS ECONOMY, they can no longer afford to be in the legal education business. They will not accept anyone this year, and plan to begin selling off buildings right after they send everyone home. [END SARCASM]
NO ONE has gotten an acceptence yet (as far as I can tell) that says nothing about whether you will be or not.
If you want to get into their heads, they probably decided to wait until they had a good number of applications so they could compare them and try to build a CLASS. Also, I would guess, given NW's reputation for business focus and liking for people with work experience that in the current economic environment they have an even greater increase in applicants this year than other schools. Many of whom may have MBAs from Kellogg School of business, which is after all, right next door.
