since early 2000's, I've heard about a statewide system being implemented, and the details have usually been the same every time I hear the 'rumor', the only thing that has changed, is that it's gone from 800 Mhz, to 700 Mhz.....
The interoperability documents I've seen have mentioned a completion date of ~2010, the 'rumors' also have hinted at a 2009/2010 completion date......
