Japanese pronunciation of the name.

SquareEnix can't pronounce the names of their own characters incorrectly. They created them, and created their names. Their pronounciation is correct. To say otherwise is pure arrogance.
did i say they were wrong? No! stop dissing ppl and read! ppl say it as "tie-dus" because of american pronunciation and because it sounds better to them. don't try and make the name one pronunciation. let ppl say it as they please, they are paying for the game. besides, in my opinion, asians ROCK!
