I am thinking that its drop will be very minor. Why? Because SSBB is a casual game that happens to have a Massive core following. I think a similiar game to this would be Pokemon, maybe GTA. The reason we saw such a HUGE drop is because Nintendo sent enough supply, so everyone who wanted Brawl day one got it(unlike in Japan where it was sold out for about 10 days, which is why the drop was less significant there). Now, the word of mouth is trickling through(I have never heard bad word of mouth from anyone where I go to college.. even my PS3 fanboy friend comes to my dorm room to play Brawl everyday) and Nintendo appears to be shipping more Wii's.

I also expect a little phenomena to kick in sooner or later(by May, brawl give alot of play time)... I we are going to see suddenly elevated sales level for the Wii quality traditional games(TP, MP3, SMG, RE4, UC). The people who are picking up Wii as we speak are going to desire games they can play on their Wii when no one is around to play Brawl with.... but this is an asside back on topic.....

 Opening week was 1.45-1.60, Second week was 350-430k, I am thinking we will see it fall to about 250-300k... Could be as high as 325k if Nintendo stuff casual channels. Which is a very small drop considering how high it started.

I am now ready to be flamed next tuesday night if(slight chance) Brawl sells 225k and all the PS360 fanboy have their moment....

I would say 260k-305k, if they stuffed the channels perhaps 325k. It would be awesome to get another week of 300k+ sales. Brawl deserves it.

It will around 190k

150k-250k. If it dips below 200k so soon, I'm a sad panda.

EDIT: talking about Americas sales only.
 

@psrock - I presume you mean US only, I really don't see it going below 200k for another couple of weeks.

I was talking Na in case n e one was confused...

I'll say 200k next week. And to your comment about "Nintendo appears to be shipping more Wiis". Last week's 200k hardware numbers are NOT a sign of whats to come. Like always, Nintendo somethings ships a significant number of consoles to a specific region. Sales are still governed by supply seeing as demand is still high. Considering supply comes at such different times (one week could be 200k, the next could be 50k), there is really no way to predict what next weeks hardware sales will be.

I think he is right about Nintendo shipping more Wiis... I think that they are going to make a spring push... Starting with Brawl and ending with WiiFit, I think Wii sales will averahe 175k a week from now until July when Nintendo will back off supply a bit(holiday stockpile, and console launches)

 I promise you 175k a week will not happen.

what are you gonna promise me : )

last two weeks have averaged almost exactly 175k, I am pretty sure the number will be close to that... remember, Reggie said the Wii will pass the 360 by June, something drastic is going to happen in NA.
