Here I want to show how the developer's decisions to keep JRPGs away from the PS3 is a big mistake on their part. They seemingly are hindering themselves from gaining maximum potential and delaying potential PS3 success.

Lets look at the JRPGs to grace the 360 so far....

Blue Dragon: 0.60million

Eternal Sonata: 0.26million

Tales of Vesperia: 0.28 million

Infinite Undiscovery: 0.46million

Operation Darkness: 0.01million

Enchanted Arms: 0.16 million

Phantasy Star Univers: 0.10million

The Last Remnant: 0.50million

Lost Odyssey: 0.88million

Now the ones for the PS3 so far....

Valkyria Chronicles: 0.34 million

Disgaea 3: 0.20million

Eternal Sonata:0.06million

Enchanted Arms: 0.16million

What does this Data tell us?

4/9 games from the 360 sold better then all the RPGs on PS3

2/4 of the PS3's JRPGs are late ports from the 360.

PS3's lowest selling game has sold better then the 360's lowest selling game.

Here is where it gets tricky....

Enchanted arms came out on 360 first, yet the PS3 version has sold equal if not better then the 360 version. And that was a really crappy game.

Disgaea 3 has outsold 3/9 360 RPGs while VC has outsold 5/9 of the 360 RPGs. Firstly Disgaea 3 and VC are both very niche with their Stratagy like gameplay compared to majority of the 360's RPGs. 360's RPGs are what stereotypically appeal to the HARDCORE JRPG audience. For Disgaea 3 and VC to outsell such RPGs shows that they have true selling power.

LO, BD, and IU are all permanent 360 exclusives. 2 of them are from an ex SE worker while one is from Square Enix. SE RPGs sell by name alone (most apparent here seeing as IU,BD, and LR are seen as terrible)

When weighing the facts:Sales vs Sales, Ratio, Genre, and date of release. I come to a conclusion. The PS3 sells JRPGs better then the 360 does.

Further validation of this would be WKC which is currently only out in Japan. THe game has sold approx. 400k-500k, outselling every other JRPG in Japan(from 360 and PS3). The game is set to out perform everyone of the 360's RPGs once it is released world wide(speculation).

So if the PS3 is such an RPG success, why don't more JRPG developers utilize it? They are only harming the sales of their games. For what ever the reason, it needs to change.

WKC is probably going to be the first JRPG this gen to reach a million. Once that happens there will be no denying it.

Eternal Sonata PS3 has not sold 0.6m
WKC has not sold 400-500k in Japan

You cant even prove your point without twisting the info. 

Not meaning to bring you down, but the highest selling game on there is at 0.88 million.

If you want to see JRPG success, look at the DS, and look to the Wii's future

Edit: Scott made a dumb mistake. Fixed now

JRPGs sell better on PS3 because Japanese install base of PS3 is 3 to 4 times larger than 360 install base in Japan. JRPGs sell around 50 to 60% of their ltd in Japan region alone. JRPGs sell mainly to Japanese gamers.

You do realize according to the numbers you posted none of those games seem to have broken even except for eternal sonata and blue dragon which barely seem to have broken even.  Which give us the conclusion that most jrpg wont be PS3 exclusive or 360 for that matter if they want to stay in business because the majority of jrpg aren't release outside of japan and majority of them in the ps2 days were considered a success to be selling 100k plus.

Unless you expect 360 games to have 50% attach rate, they won't be selling 500k in Japan. WKC will not outsell LO, I'm pretty sure of it.

I think the only conclusion that can be drawn from this is that neither console can support JRPGs and they all need to be multiplats from day one. There isn't one game on that list that looks especially successful. If it were up to me, I wouldn't be putting my RPGs on either console. There is bigger money placing them on the Wii, DS and PSP.

Why makes threads like this?

your data tells me that the 360 averages better sales even when you include things like operations darkness and phantasy star.  plus it tells me that an equal amount of people were dumb enough to buy enchanted arms.

if timed exclusive for japan have to happen they would get a bigger share ps3, thats all i see.

a timed exclusive 360 only hurt the sales.

JRPG exclusive will sell better in japan no matter what.

but its funny people put hardware sales, when in europe ps3 sell more at much 360 in all the other genders there too with a smaller user base.
