If data has already gone out to clients we should get a leak. Just like we did in the old days when NPD didn't officially release the data at all, but we still got it every month.
There are posters on GAF who get the full NPD data for sure for example, because they know the sales for niche games and such, of course they're extremely stingy with any info.
Point is I'm skeptical data went out to clients or I'd have expected a leak. Or expect one before monday.
