Actually, Sony should be doing more than just distribution in Latin America, a region of the world undergoing vast (and overwhelmingly positive) social and political change. They should be investing heavily in local studios -- e.g. Brazil-themed FIFA games, tie-ins with Lat Am's bourgeoning media cultures, etc. The result will not only be great games at affordable prices, but will also reduce piracy and encourage consumers to buy legit (because legit purchases support their local media industry) - win-win for everyone.
Sony's experience in Russia was that piracy starts to disappear around the $7,500 per capita GDP level. Basically, once consumers can afford to buy legitimate media at reasonable prices, they do so - it's easier and more convenient, people want decent customer service, etc. A number of Lat Am countries are at or close to this mark:
Chile $9879
Venezuela $8596
Mexico $8479
Brazil $6983
Argentina $6606
(This is IMF data for 2007).
