They've gotta go with Brooklyn - it would ensure a rabid following amongst Brooklynites, and to call them the New York Nets would doom them to forever being "that other New York team".
Plus, (and maybe this is just the former Brooklynite in me), I have to think that there would be more merchandising potential in the Brooklyn name. New York already has, what, seven other pro sports teams?

I admittedly was watching Baseball Tonight before turning it over to watch the Kings and Lakers. Then I saw the Nets celebrating. When I was driving home from softball tonight, the Celts seems to be comfortably winning.
