I'm also from Costa Rica and I gotta say... even if the market here is tiny in comparison to other markets, implying that numbers would be negligible... most PS3/X360 gamers buy their consoles online in the US and import them, since it's a lot cheaper than buying retail. So a big number of our units are counting as US sales.
That said, from my subjective point of view PS3 kicked X360's ass hardcore. I don't have any numbers so I wouldn't know, but all my friends have PS3s or Wiis and their friends as well. I only know of 1 dude that has an X360... 1. But oh well, this doesn't necessarily mean a thing.
The reason behind this would be PSX/PS2's huge success in the past.
