I'm really surprised the XBox360 is lagging so far behind in votes. It's what I voted for, but on second thought, I probably should have voted for the DS if you disregard preference for JRPG vs WRPG.
I'm a little confused about why the PS3 is getting so many votes though. I mean, yea, there's Demon's Souls, Valkyria Chronicles and Disgaea 3. And the (from reviews) mediocre White Knight Chronicles. And...well, that's probably about it. It could change in the future, but based on what's been released, the PS3 is lagging way behind the other consoles.
Meanwhile the XBox360 has Lost Odyssey, Infinite Undiscovery, Blue Dragon, Tales of Vesperia (only on PS3 in Japan), The Last Remnant, Mass Effect 1/2, Fable 2, Divine Divinity 2, Risen, Two Worlds, and probably others. Yes, some of those are mediocre or even poor, but the XBox360 RPG library is still far stronger than the PS3 RPG library.
