I think you've got it all mixed up about consoles in Greece Mr. PS3 gamer
I live in Greece and I can tell you that walking around Greek shops you'll see much more space given to the PlayStation 2 and the WII games than the PS3 and Xbox 360 ones. I would even challenge you to take a walk and find out that Xbox 360 seems to have more followers judging by the space provided for videogames.
All these, including your happy announcement for the superiority of PS3 sales is purely your very own speculation and only that.
Greece does not have an optimised videogame sales data, therefore, there is no way that you can really know what exactly is going on (and giving these percentages about each console's sales is outrageously wrong and childish to say the least since Greek console representatives and Greek video game stores do not reveal relevant information).
You may think that PS3 is the king of sales and I may think it is not. You can have your opinion and i can look at the stores shelves; but in the end, one thing is for sure:
GREECE HAS NOT DEVELOPED AN OFFICIAL DATA TRACK SYSTEM FOR VIDEO GAME SALES
Thanks for reading :)
