It seems that if consoles are too high it originated from before 2009. I get these numbers for 2009 (obviously I could be a week off since it is unclear what weeks are included in Gfk's 2009)
VGChartz Hardware data for the period 04th Jan 2009 to 28th Nov 2009: (which are all lower than Gfk)
Console | Wii | PS3 | X360 | PSP | DS | PS2 |
Italy

597,755
|
376,956
|
259,496
|
320,314
|
954,065

And even when adding 2 more weeks to it they're still below Gfk's numbers
