If there is news tomorrow, I will be surprised. There may be news Friday, or next week, but I doubt that Wave could know about news for a few days and postpone announcing it until after they present at Needham and on TV.
The ostensible purpose of tomorrow is to go over the recent news, share the tremendous opportunities that Wave has, and describe how Wave fits into NSTIC. Also, it would be beneficial to drop some nice names like NSA, PWC, maybe the name of the suto maker, etc.
Just my two cents.
