Okay. I've got the list and I must say..the Ichigo choice should do alright. If done well. But most of them have anime/video game experience.
Ichigo - Johnny Yong Bosch( Role known for: Adam Park/Black Ranger in Mighty Morphin Power Rangers as for anime this dude was Vash the Stampede in Trigun)
Rukia - Michelle Ruff( Role known for: Sakura Haruno in Naruto IMO bad choice)
Isshin - Patrick Seitz( Role known for: Lee Linho in R.O.D. TV )
Orihime - Stephanie Sheh( Role known for: Hinata Hyuuga in Naruto)
Tatsuki - Wendee Lee( Role known for: Faye Valentine in Cowboy Bebop)
Ishida - Derek Stephen Price (Role known for: Cyborg 009 in well...Cyborg 009).
My opinion: Okay I did some digging..ALL OF THEM have been in Naruto. Which goes to show that Viz Media isn't making much and has to use people attached to them..
