Not to smash any hopes, but that doesn't mean it will get localized. Namco Bandai also US trademarked Tales of Hearts and Innocence years ago and they never released them here. Companies trademark names so that if they ever decide to release it, no one can release a game of the same title. That being said, Xillia still does have a good chance of getting localized and I hope it does as well!
Yeah sorry but as Scott said, this means nothing. They've trademarked other Tales titles in the past and never brought them over. I'm assuming a Xillia Directors Cut of sorts will be coming out soon enough in Japan so I'd rather have them wait for that personally.
It's true about the trademarks, but I'm not too worried, Tales of Graces F just came out over here recently, so the sales numbers will likely have a large impact on their decision to localize Xillia or not.
Looking at the numbers for Tales of Graces F though, I'd imagine that they are considering localization for Tales of Xillia. I can't imagine that the numbers for Tales of Graces F would discourage them from localization. I'm not sure what sales numbers they're looking for from Tales of Graces F in the states, but I think they're probably pleased with what they've seen from Tales of Graces F. It seems to me that the Tales audience is large enough here to warrant the localization of another mothership title in the series.
I hate to do this, but these seem to be the only numbers for it, so as inaccurate they may be, at least it's something and it shows good looking numbers for the US (at least by comparison of other Tales games in the US):
If nothing else it shows that Tales of Graces F sold over 100,000 in the US on week one - I wouldn't imagine they're off by more than 27,000. That's about half the number of sales from Japan on week one, which is by far their largest audience. The numbers from the US appear to be about 29% of the total global sales of the game. Unfortunately, unlike in Japan, REAL sales numbers aren't typically published, so until Namco Bandai outright tells us the numbers or makes a comment, this is the best we have. Let's hope the numbers are good enough.
A Namco Bandai press event is expected in April, maybe we'll hear something about Tales of Xillia then. Keep those fingers crossed.
