Gosh, the last time both Cloud's voice actors, both Steve Burton and...I can't remember the japanese guy's name, was KH 2.5 HD ReMix-KH: Re Coded, which was recently last year.
Keiji Fujiwara, the japanese voice of Reno and Axel/Lea, also voiced Al in Chaos Rings III IOS/PS Vita game, Izana Kunagiri in FF Type-0, and Izzu in FFX/X-2, and I know that Quinton Flynn, the english voice actor of Reno and Axel/Lea, who again recently re-recorded his lines as Axel in KH 1.5 HD ReMix-358/2 Days, wants to voice Reno again in the future, and I'm pretty sure you guys know what I'm talking about.
Heck, if Pokemon XD Gale of Darkness had it's own anime, I'd love to hear Quinton Flynn voice Eldes, the red-haired-red-coated bodyguard/son of Greevil, and Kirk Thorn-something(sorry, I'm terrible with names) as Ardos the blue guy, as those two remind me of Axel and Saix in KH.
It'd be great and awesome to have at least the main cast of the main characters from the Compilation, and the cast of Rufus and the Turks to return for the remake and future titles of the Compilation(if it'll be made, which I seriously doubt, unforutnately, which mades me very sad).
I have no issues on who voices Marlene, since, young children characters, as we have to face it, always need a replacement as their original actors grow into adulthood, and I understand why Hojo's voice english actor doesn't want to voice him again, and, seriously, who can blame the guy? Hojo's an annoying idiot with an annoying voice that makes anyone want to just cringe.
Hojo's one of the most cringe-worthy characters in the history of film/gaming world.
