On the 360? We have:

Lost Odyssey - 5.5x multiplier and counting (101k opening, 550k LTD)

The Last Remnant - 5.2x multiplier and counting (44k opening, 220k LTD)

Blue Dragon - 6x multiplier and counting (60k opening, 360k LTD)

Eternal Sonata - 6.4x multiplier (28k opening, 180k LTD)

Kingdom Under Fire: Circle of Doom - 6.6 multiplier (36k opening, 240k LTD)

So I'd say the 360 has a good track record for >5x multipliers. I go back to the issue that we really have no weekly data for old PS2 JRPGs to really say how good SO4 is tracking vs. SO3. For all we know, SO3 could have debuted at 60k and had massive legs. Given the data we have now, I'd say that it's a great possibility that JRPGs in the US have much better legs than their Japanese counterparts. Heck, Final Fantasy VI (III US) only debuted with 30,000 units in it's first month in America.

Agreed, but that doesn't help with sales on future releases.

I can understand the much lower sales of SO4 in Japan, but for the Americas there´s no reason for SO4 to sell half SO3 sales normally. It could be due to the other big releases at the same time, but I doubt that. Launching on the wrong console seems more acceptable, but we don´t have any decent comparisons to make with the PS3.

250k Japan
400k America
200k Europe

I seriously hope you are right Mr. Stickball, because from how I see it I don't think the Lifetime sales will be that great and I doubt it will have legs surpassing that of a Final Fantasy. I would like to see this series (given userbase differences) at least achieve 50% of SO3 LTD sales in Americas.

Did VGChartz update The Last Remnant yet? For end of 2008 VGChartz had TLR at 484,000 copies sold and S-E shipment figures released last month said TLR shipped 490k by Dec. 31st, 2008. Unless the game was flying off shelves as fast as it shipped then I am pretty sure the game is overtracked here.

Is KoF a JRPG?

Japan - Seems about right and is actually very good considering userbase sizes between PS2 and 360 at time of each SO release.

America - It shouldn't hit anything less than this when userbase sizes is taken into consideration.

Europe + Others - I wish we had data for this territory.

See natural of rpg sales in NA you can estimate sales number. And you must plus install base around 12 milion at the end of year.

I don't think jrpgs are popular anymore. They won't sell like they did last-gen regardless of console. These sales are just fine for a dying genre.

agreed.

port it SE damnit

As you can see Feelplus, a Microsoft studio, helped with the SO4 development.

I doubt it'll get ported.
