Final Fantasy V and VI for DS are not announced yet but I'm pretty sure they will come out as 3d remakes.
Final Fantasy VII: Advent Children is nearly the same team as Kingdom Final Fantasy Versus XIII. This team also made all three Kingdom Hearts games out so far. The three upcoming Kingdom Hearts games are made by seperate teams but Tetsuya Nomura and Shinji Hashimoto have some supervisory type involvement. Anyways, I don't know if they can announced another FF VII cg movie since if they did it would probably be from the same team as the FF VII: AC movie, and this team is busy making FF Versus XIII right now. I don't think they'll announce a FF VII remake yet, it's a bit too soon and they haven't announced a FF V or FF VI remake yet. I don't know what the announcement is going to be but considering somebody from Square Enix already said that there is going to be a big announcement, I'm excited.
Maybe they'll announce a Usa version of Final Fantasy VII: Before Crisis. Maybe a new FF VII game that isn't a movie or a remake. Or maybe the news is mistranslated and/or misunderstood and this news isn't related to Final Fantasy VII. I wonder if it's possible that this news came out before the FF XIII Xbox 360 announcement was made and this is the announcement they were talking about but it got pushed forward to E3.
If you are looking for another idea here's a big one, maybe they will finally give more information on the mmorpg that the FF XI team is making, code named Rapture. Maybe they will tell us what Final Fantasy Haeresis XIII is. Or maybe they will announce that these two games are the same game? I'm excited!!!!
By the way, I want a Usa release announcement for Sigma Harmonics!!!!
