I just found a gamasutra report with first week Japan sales for Fatal Frame III:
http://www.gamasutra.com/php-bin/news_index.php?story=6133
Fatal Frame III, Japan, Week #1 - 38,617 (number from Media Create)
If you find data for other games/weeks, post it here so that we can form some sales expectations for the new game on the Wii.
UPDATE - Thanks to Bruno, here's some Famitsu data for the first three games. This data is all for Japan:
Fatal Frame:

LTD after 3 weeks - 42,195
Fatal Frame II:

Week #2 - 8,932 (LTD to week #2 - 50,938)
