I can understand Japanese so having the Japanese audio track would be nice, but I will not be surprised if it is not included. One of the things I do like to do is compare the translation and see how they decided to translate out everything. Since everything spoken in Japanese will not always work well directly translated to english, I like to see how they decided to localize certain lines.
I also like to see what they changed, for example in FFX at the very end in the Japanese version Yuna tells Tidus "Thank you", but in the US version, she tells him she loves him. IMO that is a big difference in meaning there, so I always like to see what got changed.
