Yeah, if there's no sign of the sequels coming out and no one plans on doing any fantranslations I'll probably play 2 and 3 in Japanese. I'm glad I had this game as a primer. It's a bummer though because I hear the recruiting and customization of your team is a lot bigger in these games, whereas here we basically had to mostly stick with storyline characters if you wanted anyone good on your team.
The release of the 3DS may very well decline any chance of any more localizations for this series. Especially because it's still not out in the UK and won't be until who knows when, and I feel like that was the 'main' market they were going for with this localization.
Hopefully there is enough interest in the series for a fantranslation now!
