I think he's referring to the fact that Vesperia is the 2nd bestselling Tales game in the west. In other words, they're alienating a pretty large number of potential buyers in the west by ignoring Xbox.

Yeah, Sony has to be paying them for exclusivity. Vesperia sold 500k units (not including digital) outside of Japan, that's alot of potential sales that they're passing up by sticking with single platform development. Assuming that the average profit per copy sold was about $15, that's $7.5 million in profit they're passing up per game. And there's no way that the costs of porting between 360/PS3 are that high, and porting between PS4/XB1 is easier and cheaper than porting between 360/PS3 was.

Oh you dont think he is going to moderate me do you?  YOu do know he is the one that told me to put it in the poll right? ;P

Yep, they say it's their choice to concentrate on singleplatform development. I just don't think that was a smart choice if they're not being paid by Sony for exclusivity rights. I think it's telling that the 2 bestselling Tales games outside of Japan are Symphonia and Vesperia, both of which released on platforms other than Playstation. And like you said, Hideo Baba believes that the core fanbase is on Playstation, so therefore he must not consider fans in the west to be a part of the series core fanbase. Vesperia and Symphonia sold as many copies or more outside of Japan as the series average in Japan.

I don't know, it just kind of seems shortsighted to me to ignore so many fans in the west when the Japanese console market is clearly shrinking. I think multiplat development is the best course they could take right now, especially since porting between Xbox One and PS4 is so easy and cheap. We've heard indie devs say they got games up and running on Xbox One for just a few thousand dollars and in just a few days, I'm sure that Namco Bandai could get future next-gen Tales games running on Xbox One without spending too much more time or money than those indie devs are, maybe a month or two and $50,000. And the potential reward could easily be 200-300k more copies sold. That's alot of sales that they're passing up in my opinion, a few million dollars worth of sales. I fear that if they stick with Playstation only development this generation while the Japanese console market keeps shrinking, they'll either end up dropping localizations to cut costs, or end up switching to mobile development eventually. Just like Sega has done with Yakuza, Phantasy Star, and Valkyria Chronicles. 

We shall see. What worries me is the fact that the sales of the PS3 Tales games aren't that much higher than the sales of those 3 Sega series I listed were when Sega decided to either drop localiztions or drop console development. Heck, Valkyria Chronicles actually outsold the bestselling Tales game and it still ended up switching to mobile, and then later lost it's localizations as well. I fear that the shrinking Japanese console market could do the same to Tales. We'll just have to wait and see if the PS4's success in the west can compensate for the shrinking Japanese console market. 

There's importing.

Do they come with English subs and text?

If you can read and speak Japanese. Sadly I can do neither, despite trying to learn several times. Sometimes you'll get a fan translation, but that can take months or years, and sometimes fan translation projects completely stall, as we've seen with the Sakura Wars franchise.
