Hmmm. Well, this doesn't really tell us much that's concrete, but we can speculate on some things.
VGC has Killzone 2 currently at 600k in the US and 1.16 mil WW. Do we think that tL&tD sold more than that? With GTAIV currently at 6.9 mil WW, if only 1 in 5 of them downloaded the expansion (1.38 mil), then that would total more than K2 sold up to now (though it was released some 11 days later).
These are just numerical analysis. I've come to no conclusions. Please don't flame me.
