Someone brought up that Puyo Puyo Tetris might simply be an Asian-English release and nothing more.
Which is fine; I can import twice, and I'd like something Puyo Puyo-related on my PS4 (didn't import the PS4 version since I already have it on PS3, and all the DLC), but a Western release would have been nice.
Now, English dub? I'll be happy if it happens, but if not, I can live. Honestly, if they brought it to the west, they'd probably be wise not to dub it simply because of uncertainty as to how well it'll do. I've heard dubbing isn't cheap, after all.
