You don't need the nav for games like sports championship and PS move orientated games, the nav is made for the core titles that require analog movement (which you can use a DS3 for) and besides I assume you can use 3 navs and 4 moves since the navs are the same as the DS3.
Also for those that said some move games require 2 moves, well you can play them with one move, the 2nd move just adds more immersion to the game.
