I'll be honest with you - I think both sides are best quit of each other. Glendale is still run by small-town goofballs in various stages of corruption, and IA are like boardwalk discount Rolex salesmen. In another reality they might have gotten along swimmingly - Gary Drummond and Ian Hugh could swap tips about the best way to pull other people's strings - but as things stand the farther each gets from the other, the better it is for everyone.
Glendale will go forward with one less barrel to be bent over (leaving their current running total at, what, five?). IceArizona will go forward looking for subsidies from some other Phoenix city and, failing that, they'll either shoehorn themselves into the Suns' new barn and say sayonara to most of their revenue
or they'll pack it in and load the moving vans, blaming Glendale for everything the whole way out of the state.
