ok some of your predictions are realistic. Week one sales of 1 million WW are quite possible. Europe and America could see those hardware sales, but I very much doubt it. I think you've been confused by the recent holiday sales. There is absolutely 0% chance of 800k for the month in Japan. Considering MGS sells about 800k lifetime in Japan, predicting that 800k consoles will be sold (and going by your 100% attach rate theory, more than 800k copies of MGS) in one month is completely ludicrous.
And there is no way that it will remain number 1 in all three territories for 4 weeks in a row.
Help! I'm stuck in a forum signature!
