No spoilers for those of you who've braved Japanese Cold Steel 3 please (if you must do put them in spoiler tags), but we also seem to be getting PS4 remasters of Sen 1 and 2 as well all due in September of next year.
I still need to finish Zero & AO before I can even start my Japanese copy of CS3. Oops.
Any discussion however may contain spoilers of Trails of Cold Steel's 1 & 2 so be warned.
