did you see the release notes? they are on the firmware download page.
it's a CDJ firmware update, why would they mention rekordbox? a lot of your list is just your wishlist. it's not really representative of what the majority of the users need right now (ie greater stability, bug fixes).
traktor was updated last week to now work with the nexus. serato need to release an update too.
the aero features would be nice to have but were never mentioned as being included with the nexus so it would be a bonus if they ever get included.
