Galvaniser, I don't know if you heard but Matusno left Level 5 after he finished Crimson Shroud.

It's possible a return to Sqaure Enix is on the cards...

Maybe he is returning to Squenix to remake Vagrant Story or work on FFXII HD.

Unfortunately not. I've asked him on Twitter, he replyed to me this morning.

He has said he will NEVER go back to Ivalice. He wants new projects.

I want to ask him if he will ever go back to Square Enix, since he rumoured to be the scenario writter for FF15.

However I very much doubt he will answer that question.
