I'm pretty sure VII Remake is already on table for years.
I guessed sometimes around X Remaster because IIRC either Kitase or Nojima around that time when asked expressed that remaking VII is not easy due to amount of materials need to be checked so all the stuffs truly connected from BC-CC (pre-7) to AC-DC (post-7).

Around XV you could say what's left is deciding how to achieve balance of development, story and gameplay as they initially thought of doing open world in hope of doing remake in "3 discs" format like OG but later expressed they're glad Midgar is enough to summarize things because it helps the development (OG Disc 1 ended in City of Ancients). Perhaps indicating they learned to not be too ambitious after reflecting on XV development cost.
