I'm from Sweden so excuse my bad english ^^ :toungesmile:
but It is all true. Ven is a shorted name for ventus meaning wind and he is is relating to sora (sky). Nomura had said it. Aqua and Terra is their truly names. Aqua=water and Terra is the latin word for Earth. Nomura gave no details about the color of Terra's eyes. It was blue but now gold. he said "I think everyone's imaginations are pretty capable so please try and anticipate a lot of things".
His final comments regarding the three warriors' names were that the names of Sora, Riku and Kairi are meant to signify Sky, Land and Sea, while the names of Ven, Terra and Aqua represent three different properties of the world: Wind, Earth and Water
I do wonder who MX apprentice is though. in a recent trailer Terra knocked his helmet off but the trailer ends before his face can be seen. he wear nearly exact the clothes riku had in Kh1. and a keyblade looking like Soul Eater but i don't know. And in the end of the BBS trailer. King mickey comes and is looking ready to fight MX. And he is wearing different outfits than before. And his keyblade isn't the kingdom key. it is the Star Seeker that is associated with Yen Sid. just saying what i know.
best Wishes here from sweden ^^ btw here in sweden the time is now: 09:30 in the morning ^^
