I was snooping around Bamco's website and found the following link:
http://www.bandainamco.co.jp/en/ir/financial/
The page contains several Bamco financial reports. In every "Financial Highlights" report 2006-onward, you can see the total units sold in that year for some of their top-selling games. For whatever reason, for some games they only list one or two particular regions, but eh. It's interesting to compare it to some VGChartz data. For starters:
-Combining the "Highlights" for the fiscal years ending 2006 and 2007, Soul Calibur III sold at least 1.42 mil WW. VGC hasn't tracked SCIII at all, so that # is up from, well, zero.
-Combining the "Highlights" from the fiscal years ending 2006 and 2007, Tekken 5 sold at least 1.92 mil units in Others (the first number in the 2006 fiscal report, 1.177 mil, only counts Europe and not the other Asian territories. The second number for the Platinum version in the 2007 report, 737k, counts all of Others). VGC has Tekken 5 at 0.49 in Others, so that # is off by about 1.5 mil.
-From the 2009 report (the most recent one), DBZ Burst Limit for PS360 has sold 730k in Japan and Others. VGC has the EXACT same numbers. 
That killed a good 10 minutes. 
Anyone else can feel free to look and see if they find anything interesting.
