Greg can speak to this better than I, but udev is most certainly intended to completely replace /dev. The thing is that not everything exports the required information in /sys just yet. If you start up udev and then run the script that comes with it that parses all the pre-existing /sys entries, it will build a pretty decent set of device nodes. Eventually it is intended that this will be mounted at /dev, which could be an on-disk filesystem or else a tmpfs-based one. Once all the information is in /sys, then static /dev will go away forever. (Which is good, since device numbers will be random in 2.7.)
