Apparently it's an enhanced mobile port:

In short -- An enhanced version of the smartphone game Tales Tactics Union, but with a seemingly downgrade in graphics.

- graphical downgrade compared to smartphone version? (lol)
- 8 characters per battle
- game is 60% complete.

it's a port, and they said the article calls it an enhanced port, with voice acting, new cut-ins and new art/forms for Tern and Nacht.
And again, no mention about the graphics in particular.
They show 3 in-game shots, and to me... they're identical. Maybe the person who made the comment referred to resolution, OF COURSE that would be worse, being now in 400x240.
