So, what do you guys think for Metroid Prime trilogy sales (worldwide)?

I'm guessing first week about 250-350k (tho I am leaning more to 250), lifetime 1-1.5 mill. I would love for it to be higher as the games deserve bigger sales than Halo, but it's not going to happen.

I actually totally agree with you, also wish it would sell a lot more then that but I just don't see it happening.

I hope it'll cross 1 million lifetime, and I kind of expect it to. Not sure about first week, but I can see it coming around to about 200k lifetime.

One Million??
I really don't expect such a great sales like this! Obviously I think Metroid deserves big sales (millions if you want), but remember that is a special edition with 3 old games, so a lot of consumers got it years before.
I think 400-450 k are more realistic numbers...

I think a lot of consumers that got it years before will want to replay with new controls. I am one of them. Metroid Prime sold almost 3 million copies, so I dont think 1+ million for MPTrilogy is that farfetched.

If Nintendo advertises then it could sell 1.5 million.

They won't though so I'm guessing around 750k

so 200k in America first week, Europe will likely add another 50K or so. so 250k seems reasonable first week.

Numbers for pre-orders are not yet at 100k in the U.S, and those numbers are totally unknown for Europe (and usually buys less units of Metroid series), so expect 150k for the first week (U.S and Europe sales combined) and 450k lifetime. Just look the actual sales for Metroid 3 Corruption on the wii. It's a great game that is not taking great numbers for the pasts months. I would say that the total sales for the third part are now at 1.5 million 8quite good), so, you really expect such a great boost in sales? Why? Only because of the new controls? Obviously three games for the price of just one it's a good temptation, but for great graphics, and great controls there is MP 3 Corruption, and nobody is buying it (and less before the announcement of MP Trilogy).
I really would like MPTrilogy could sell a lot, but i don't think so.
Instead of sales, MP is one of the best franchises in videogame history!!

Hopefully Metroid: Other M can bring some more players into the Metroid fold with (what looks like) its more action-oriented approach, and then we can get a new smash hit first person Metroid for Wii's successor...

I'm really tempted to pick the trilogy up.....just too many games and not enough time :(
