Think the context a lot of people miss with regards to Falcom and western localization and the like, is that Falcom only sees something like 15-20% of it's total revenue from western sales.
They won't abandon that market, but needless to say, in terms of priorities it's bottom of the barrel, and it shows in terms of every action Falcom makes with regards to the west. The other thing I will say is, NISA isn't Falcom USA, and as such it's very possible that Falcom came to them with an idea to start work on localization as games are in development and NISA declined.
NISA works on and localizes more than just Falcom stuff. I feel like these demands of Falcom letting localizers work on their games as they're in development assume that the localization partner in question (NISA) would actually want to do that, which to put it bluntly we simply don't know. The issue is way more complicated than "FALCOM SHOULD DO X", and I'm not defending them because frankly, my interest in this series couldn't get any lower if it tried after CS4, but that is the reality that's at hand.
For the newest Trails titles, you will always wait a minimum of 2 years, and you can bank on it for the Forseeable future.
