I remember doing this same type of thing with Monster Hunter 3 back in August.
Its looking good so far, but I wouldn't doubt what would happen towards Christmas in NA.Stock will probably be drained in many game stores by the time December 25th is over. Wal-Mart especially is promoting the Wii and DS LIKE CRAZY so sales may actually remain consistent (>25% week after week)
In Japan, it was a virtual sell-out with 86% sellthrough first week.
