Holy crap. Somebody must have messed up here. Probably not VGChartz or Media Create, but one of the middle men (dunno what to call them). VGChartz has total DS sold for the period at 314K. 60K could easily be DSL, which would mean that VGChartz has DSi at 50% of what Media Create has it at!
In a sec, I'll check famitsu.
Okay, Famitsu.
Week ending 16th - DSi 81K, DSL 7.3K
Ending 17th - 102K DSi, 18K DSL
Ending 9th - 93K DSi, 13K DSL
Ending 2nd - 171K DSi, DSL 18K
So total:
DSi = 447K
DSL = 56K
Edit 2: Yeah, MC has DSL and DSi as the same, meaning they are spot on with Famitsu.
The numbers I originally posted here doesn't make sense. When I used the HW table, I got that. With weekly though, it is 502K. VGChartz is straight in line with this info. My bad!
