In the end I think we can all agree that SMTVV's only last legacy will be how gay it was.This game was nothing but a beta test for VI.
The demon haunt is bare bones and will obviously return revamped now that people liked it. The combat was refined just so it can be used over again. The only thing they didn't bother with was dungeons because VV was their first attempt at a open world like format. It will also be expanded in VI.
People will look back at VV and forget it existed outside of pic related. A wasted mainline entry.
