Sigh there's no point in me arguing something that hasn't been announced.  We'll see at TGS.

 Actually, if anything, it will be. It sold more 360s to the Japanese then any other game so far in history. It already has a legacy all its own, and as far as the 360 fans in Japan are concerned, its one of they're saviors. I haven't heard anything about them alienating they're audience. They've only said they are trying to gain the west audience as well, or in other words, expand they're audience. 

What are TotA and legendia remembered for? 

ToV will be remembered.  I doubt the Japanese will forget it.  Look at Blue Dragon(another 360 exclusive JRPG), that game spawed a 52 episode anime series that was so popular that it got a sequel series so that tells us that the Japanese haven't forgotten about BD.

ToL wasn't that remembered at all but TotA was remember by Japanese fans as the best game in the series, atleast until Vesperia came out.

Why do you think they would do such a thing? Is it an attempt to force the 360 down Japanese throats? I wonder if MS paid them. I have no proof, but it could very well be a payoff for such a prestigious core title as ToV by the Symphonia team to be exclusive on 360.

Come to think of it, I think legendia was known for being the worst in the series, lol. Abyss didn't really have a big legacy though, like say, moving hardware like Vesperia and Symphonia did. Though it was the best in the series, and still my favorite JRPG ever. So it had more of a legacy within its fanbase, but not all too much else.

@Soriku

Eternal Sonata doesn't have the "Only on XBox 360" though...

Nope. The "Only on Xbox 360" is quite final.

Look for yourself:

Those games will be released on PS3 this year but these will never:

Tales of Vesperia didn't sell all that much compared to the other Tales games. It would have sold much better on PS3.

Anyway, I really don't care if that game doesn't sell as much as it would have in Japan because I practically bought a 360 for this game (well that and all the other JRPG).

@Godot Mass Effect and Gears are on PC. So I guess that "only" excludes pc right?

I seriously doubt Tales of vesperia will be going to PC. So its pretty assured that its JUST for 360. 

THEN AGAIN! Looking at my Symphonia game here, it says "Only For Gamecube". Though it went to PS2. So who knows. All I know is that if it IS gonna come out for PS3, it'll probably be 2011-12. If you want to wait 3-4 years for a game that probably is never coming out for PS3, ya know, be my guest.
