Where will steve nash go next year?? miami/ny or what?

What team would be his best shot at winning a championship? I really like NY but they have billups and miami only have chalmers to trade. Even then I can't see miami winning it all without a decent big man. Orlando would be a great fit as well. He probably still have 2 even 3 years remaining considering his numbers barely declined and most of it is because he doesn't have much to work with.
