In KH3D and KH3 i think we could possibly see a younger Master Xehanort because he will probably be ressurected in his prime and become stronger also because i think i heard this was the guy who voiced MX in english versions last project (i think his name is Leonard Nemoy excuse me if i spelled it wrong) and that would be the onlly way i can think of to change his VA i also think it will be interesting to see a younger MX.

They wouldn't change MX just because of different VA's. Look at Ansem SoD. The guy who voiced him in KH1 only did it in KH1. For all the other games Ansem SoD was voiced by Richard Epcar. They'll probably just pick someone else to voice him.

They used David Gallagher for his one line at the beginning of BBS. He was uncredited though. Maybe they'll use him.

Mmmm... yes, I thought it was David~

 

If he has a larger role I don't know if they can really keep using David. Especially if he's in a scene anywhere near something to do with Riku. He tried really hard to make it not sound like Riku, but after listening more than once it really sunk in. Unless, in some wacky way, Riku and Xehanort are more connected than we thought. =w=

 

I definitely want to see more of y!MX. And while I really hoped that they'd bring Billy Zane back for re:CoM (and I will always prefer him), Epcar ended up being just fine. If Epcar is -capable- of sounding younger, perhaps he could even do it.
