Just wondering why it's a issue releasing these games in English? Is it mainly due to fear of bad sales and translating the games since they are heavily text based.
Okay, here's the thing.
The first Trails title was released on PSP by XSEED in 2011. It sold abysmally.
Then, when XSEED was able to release a Steam version a few years later in preparation for the release of the second chapter, that Steam release sold a lot more than expected. It did pretty great.
However, Trails in the Sky SC is the biggest Trails game. It has 2.5 million Japanese characters in it. It is a god damned huge undertaking to translate, and it also shares the same world as other games in the series, so you need to make internally consistent terms and names for things that will pop up later or which already appeared in it. It took four years of translation for SC to get out the door, and it was a ridiculously stressful ordeal.
Now that SC is out, here's the thing. We were four games behind! Holy shit, how do we catch up?
Now, cue Falcom coming in re: XSEED and going 'what the fuck man, we're on Cold Steel by now, we designed Cold Steel as a great jumping in point so PLEASE HURRY THE FUCK UP and localize Cold Steel before the PS3 dies.'
XSEED, having learned a ton from the localization of SC and having a way slicker workflow (and Cold Steel is a smaller game than SC) was able to announce and release Cold Steel the same year it was announced. Not only that, Cold Steel II is coming to the West in 2016 so we'll at least be 'caught up' even if we skipped a few titles.
Now here's the thing - in this process, we have skipped the third Sky title, Zero and Azure. Zero and Azure are a duology that takes place in a different nation, Crossbell, which is close to both Erebonia (where Cold Steel is) and Liberl (which is where Sky is.)
The problem here is that all three of these titles will have to be PC only - Trails SC was XSEED's last PSP title, and Sony is shutting down the PSP store anyway so yeah. Not only are XSEED's standards high enough to not fuck with their fans by giving them the PC versions that currently exist of Zero/Azure (both are Chinese outsourced PC ports running at a shitty resolution, the latter having Chinese DRM in it and not being released even in Japan,) they would need to do a ton of programming and tweaking and re-insertion of higher quality art from Falcom, et cetera. It's just a big fuckery right now.
The benefit to localizing Cold Steel now is that they're PS3/Vita and Falcom wants them to hurry the fuck up (which they did) and bring the West into the series.
