@rikitikitik, I think their shipment numbers are tied to the amount of orders they're receiving from retail.
About your numbers for RE 4, the game just launched in Europe, if it made the top 10 it was on 2 days of sales. So your 100k estimate seems like a completely random number since there is almost no data yet. Japan most likely will get to at least 100k lifetime sales (VGCharts has it at 82k now and still selling 6k a week, so 100k seems low taking those numbers into account) and if RE 4 manages to sell 150k in it's first 3 weeks in the US then reaching 300-400k lifetime sales in the US is the likely scenario. So I'm pretty sure those RE 4 numbers will turn out to be very conservative estimations and I have no reason to believe the Umbrella Chronicles estimations are any different.
