I doubt they really know that much about the sales numbers, they will know what they shipped but not what has been sold.
MS was possibly only able to report because they buy full NPD numbers which would have quickly given them preliminary sell through results whereas I'm not sure if T2 buys them.
Just speculation of course.
Edit: Also from what I've seen and heard the early sales of GTAIV have not been underwhelming, the game has, at least early on, sold very well. Now we only have to wait and see if it has legs like its predecessors or whether its found a more focused fanbase like most big series end up having.
