Some first day numbers from http://sinobi.ameblo.jp/ :

Kidou Senshi Gundam Seed: Rengou vs. Z.A.F.T. Portable - around 50k [PSP]

Powerful Pro Baseball Portable 2 - around 20k [PSP]

Naruto - around 60k [PS2]

Pro Baseball Hot Star 2007 - around 10k [PS2]

Final Fantasy I [PSP] (04 -19 -2007) - 100k copies already preordered *

* (Babel fish... I'm not sure about this one - if y-koron or other Japanese speaking user would check this info it would be great)

Thanks for the info.  I wonder if this will help keep those PSP system sales up for another week.

I have no info about FF1 for PSP. What I know is that only FF1 for PSP is remake of GBA version...

And prediction... The sales of Phoenix Wright 4 will be more than 100k only first week. It is because limited edition and normal edition with headphone have been almost sold-out.

# The number of orders is about 400k and more than 100k are seemed limited edition and normal edition with headphone.

# And it of Mario vs Donkey Kong is about 200k.

First day sales? Not bad but compaired to MH2 nothing. I am surprised though I am a Sony fan. The PSP will do great this year because of the upcoming 3 FF games. FF1, FFT, and FF7:CC.

 When do they come out in Japan?

Well sems pretty good for PSP, that system is coming alone quit good even if it can't match DS (but of course that system is -ing insane). I personallly think that PSP can continue to do some really good numbers this year.

50k in first day for gundam seed psp,I think it's a good start!

FF1 : 4/19 (same with Paper Mario)

FFT : 5/10

FF7:CC : I don't know ( not decided )

The number of first shipment of Gundam Seed is about 100k. Probably second ship is already in the shop. Probably first week is about 80k~90k (prediction is based on the PS2 version about 200k)

@ sayen25

Pretty solid but previous Gundam for psp achieved an impressive number of almost 170k copies sold during week one....

@ y-koron

How about this - PSPを使ってリメイクされた「ファイナルファンタジー」。メーカー自ら「15万本程度も売れれば上出来」と言っていたのだが 受注で既に10万本を突破したようだ。Isn't it about preordered FFI ? Thanks.

How many pre-orders did MH2 have before launch in Japan?

 Around 500k.
