Okay, so lets take a quick look at what RPGs are actually confirmed for both systems to see which one will more likely be the best at JRPGs, okay?
Xbox 360:
Tales of Verspia (Namco, major JRPG IP)
Infinite Undiscovery (Tri-Ace, same company that makes Star Ocean)
Cry On (Mistwalker)
Last Remnant (Square-Enix)
Magna Carta 2
Playstation 3:
Final Fantasy XIII
White Knight Story (Level 5)
Valkyire of the Battlefield (Sega)
Last Remnant (Square-Enix)
Hmm. It doesn't sound like the Playstation 3's confirmed lineup is any better than the 360's - I chose not to include Blue Dragon and Lost Odyssey 2, as both have pretty much been known, but not totally confirmed.
So exactly how is this list so much more definitive for the PS3? Yes, the upcoming list might be slightly better, due to FFXIII, but the fact that the X360 has quite a few former exlusive JRPGs negates that advantage.
And like I said, the PS3 WILL NOT be the JRPG home of consoles this generation - everyone has jumped the Sony RPG train - Namco, Nippon Ichi, Square-Enix, and other companies that made RPGs almost exclusively for the PS2 are not making their uber-IPs on the PS3.
Also, if you had the grammar of someone older than a 13 year old boy, would make me respect your opinion as you *might* have been playing RPGs as long as I have...but I do doubt that with your additude.
Back from the dead, I'm afraid.
