It appears to be a bigger game than Phantasy Star Portable because:

1) It's not a port - Phantasy Star Portable was basically a port of Phantasy Star Universe

2) It was developed internally - Phantasy Star Portable was outsourced to Tales of the World developer

3) Online Infrastracture - Phantasy Star Portable was ad-hoc only

4) It's on DS

So...predictions for first day/week/LTD anyone?

*Just for reference, Phantasy Star Portable's first week was 342,000 (according to Media Create)

I'd like to think it'll hit 500k on week-1. I hope it does well, because I want it to come to the US.

at least one unit.

I'd say atleast as well as Phantasy Star Portable if not a little better.

Some games do sell better on the PSP than the DS... lets see if this is one of them.

I do wonder how well a Monster Hunter on the DS would sell?

I think it will be huge in Japan, prolly decent in US.

That sounds sensible.

This isn't the price is right it's sales predictions!!!

Anyway I'd say about 500k in Japan would be a safe bet.  Though I would say 700k+ is not out of the question.

First week or LTD?

First week, portable RPGs fair well first week in Japan, Monster Hunter, Crisis Core, and a few others have done really well and those two sold over a million first week.
