I found an article about PS3 sales in Poland. It comes from Sony PlayStation day conference. It says:
PS3 sales:
36k (apperently it's error, should be 32k)
PS3 forecast (end of fall)
over 50k
46% of PS3 owners uses PSN/PS Store
GTA4 for PS3 is outselling the X360 version by ratio 3:1
They also say about silver MGS4 bundle, new Singstar, Heavy Rain and new PS2 version.
If someone want to read (its written in Polish)
