from all the artcles we've been reading so far, it does seem a little low for GT5. either way its still good. i wouldnt be surprised if there are adjustments in the future. what about that 2.4 million first 4 days article the other day? there seems to be all sorts of numbers flying about at the moment.
anyway it doesnt matter, polyphony always put the sales on their website for everyone to see.
