short translation from finnish:
''Gran Turismo 5 comes before christmas
We are getting our hands on Gran Turismo 5 in coming months. This was revealed from press report of Nordisk Film. Press report says that PS3 slim comes to market just in time before big holiday blockbusters like Uncharted 2, Ratchet & Clank: Crack in Time and Gran Turismo 5.
So it seems that highly anticipaced game from Polyphone Digital comes to market before christmas''' /End of translation
Hopefully this is true. =) Slim PS3+GT5+Europe = sales will explode.
