In an interesting interview between FFDream.com and the couple, Yoshinori Kitase and Motomu Toriyama, the french fansite came back with a good information : "If we did want to do [a FF VII Remake], we have to sit down and think carefully what would be the best possible way to do that. It could be a remaster like X/X-2 HD Remaster or possibly a full remake. This time, it’s our first ever HD Remaster attempt."
A open door for dreamers for sure.
The interview focused on FF X HD explained that a Final Fantasy prequel with Braska, Jetch and Auron was very close to be produced.
