I figure that the reason why the Live Arcade and WiiWare/VC games aren't added into the full charts is because of the relative inaccuracies of the tracking methods. Don't get me wrong but I think that ioi wants to keep the integrity of the site by having the actual charts being as close to the real data as possible.
But I agree with you. I'm all for having it added, or having a separate main page chart with the sales data displayed. They just need to find a way to track PSN info.
