Ok confesssion time, as I was comparing the numbers for spirit tracks between famitsu and mc, it seemed like they didn't agree on the week 28/12/2009, then it hit me that Famitsu has 52 weeks for 2010 and MC has 53 weeks as I remembered the whole ordeal over the PSP/DS hardware situation. God I felt stupid, but I'll be damned if it wasn't fun. It's also weird that Famitsu and MC hardware numbers for Nintendo hardware on that particular week was very different.
Wii 216,933 163,855
DSL 16,493 17,388
DSi 227,379 92,461
DSiLL 0 70,643
PS2 5,111 4,023
PS3 131,523 114,368
PSP 129,438 132,911
PSPGo 4,840 3,903
X360 6,937 6,878
Seriously, 227k and 92k? That's a pretty big discrepancy
