It’s true, there is a new Encyclopedia in the works. A volume that will update ongoing entries. Stuff that hasn’t changed (i.e., “hydrospanner”) won’t be duplicated in this second volume. A pub date hasn’t been set in duracrete yet, but we’re looking at Fall 2008 as a possible release time. The format will be the same as the first volume, to keep it as a “set.” That’s about all that’s been discussed at this point.
Also, the Coruscant Nights trilogy is being pushed back to 2008. Better than a year between each volume for a paperback trilogy, I guess.
