I just got the letter announce that ArcGis 9.1 will be shipping soon. I was reading through some of the changes. Just when i thought they were making all the good stuff availble as a extensions it seems that they are doing the opposite and consolidating extensions back into ArcGis. ArcPress, ArcScan, and Maplex will be standard with ArcInfo. ArcGIS street map seems to be added as well. For more info click here
