That's almost certainly the "questionable source" from the OP. The reason it's questionable is that they do very little polling of retailers themselves, they mainly just guess at numbers. And when a company that does poll retailers releases numbers, VGChartz edits their numbers to match, so they look more accurate when people look at older releases. NPD had to stop releasing sales for games outside the monthly top ten because they were tired of VGChartz stealing all their numbers. And worst of all, VGChartz tends to do worst with low-selling games, as in anything that doesn't sell 100k the first week.
NPD does do much broader-based retailer polling, so their numbers are pretty solid. But they haven't released their March numbers yet, we'll have to wait until April 15 for that. And like I said before, we'll still have to hope for a leak.
