That's why its unsure this time.  However, the unknown factor in DQIX case this time is that its on the DS.  It may even exceed expectations and sell well beyond 4 million in its lifetime.

i suspect DQ will hit first...speaking of which, when is that game coming the NA? i havnt heard anything yet, course i probably just missed something.

As part of one of Wadas big 'calm people about FFXIII' announcements a couple weeks ago, he also made some statements and projections about SE in the upcoming fiscal year.  And one of them was that he [referring to the company] didn't see them getting to an international release of DQIX until sometime 'next year' (which would be sometime after March).

So if anything, chalk this up to another 'we don't care' from SE of Japan concerning Dragon Quest.

MH3 will reach 1M in the first week of november, while DQ9 will achieve 4M the first week of October, that's my bet.
