1 million in American sales in the first week, brings total so far up to 6 million.
Also, in order to compare Japanese sales with Ruby/Sapphire: D/P is currently 800k ahead of where R/S was this far in release and selling about 3k more a week. Expecting 6.5 to 7 million Japanese sales isn't unreasonable (compared to 5.4 mil for R/S). However, its price will depend on American and PAL sales, which have a much smaller DS install base than the previous GBA one.
