Just a heads up, Kingdom Hearts 2: Final Mix+ is coming out next spring in Japan.
Its going to have full English voicework (but in-game text will still be Japanese) and include a 3D remake of Chains of Memories (not sure about English in this one tho).
Obviously this is only something to consider if you can play imports, but I picked up the Japanese release of KH2 at launch last December, beat it, and was contemplating getting the US version until I heard about the redux.
