A pokemon RPG on wii will sel millions, MILLIONS!!!

 Isn't that what SE does now a days?  Just have all the developers pitch RPGs, and the best one gets moogles added and gets the Final Fantasy name while the rest become new Ips?

if you count portables then alot of them that are released on DS

It's sad...but Japan has been slow producing ANY kind of (console) game this generation (aside from Nintendo itself).

Don't we already have one of those? (Hint: It hasn't sold a million.)

 Wow, I thought you could recognize an rgpg when you saw it, this isn't even close to it.

LO sold around 700 000, but why you care so much about JRPGs? WRPG are much better. This is my opinion of course, but I know many people which were playing JRPG and now they shift to WRPGs.

Think people, think!
The only two consoles able to support JRPG just reached 1.5 years old. There's no way JRPG that can be a commercial success are released before a console has 1.5 years. They usually appear after that time, if only to have a sizable user base.
Dragon Quest Swords is an exception, as it sold well despite being a bad game: it's actually a big success, as it didn't cost a lot to make, but raked in lots of profit.

The first ones are coming, and the XB360, which is more than 2 years old, had its JRPG, but unfortunately it doesn't have the userbase to sustain it.
The userbase needs to be in Japan, as that's where JRPG mostly sell.

As for commercial success, it can happen with FFXIII, but I doubt the genre can survive on HD consoles. The problem is that the current values of the HD consoles imply more epic JRPG, with better graphics, better cutscenes, better sound, ... All of this cost more money. Unfortunately, as we've seen, sales are less or equal to last gen. But last gen it wasn't so expensive to make games. So the devs won't be able to sustain the genre. Look at Disgaea 3! HD console is useless for such a game, but that's what you'll start to get. Look at the raise of cell shaded JRPG this gen: it's cheaper to make.
Not everyone can lose as much money as MS to make JRPG that live up to the console they are put on.

Well Crisis Core is closing in on 1.3 million and its still unreleased in Pal teritories ... is that a success ? IMO yes :D
