Yeah I think if people want a like-for-like facsimile of FFVII then they're going to be disappointed. It's been 20 years, there's nothing wrong with changing and adding things. For one, they're surely going scrap all of the towns and map layouts as they were designed for PS1. If they have brand new HD layouts for the likes of Midgar - and have it be a real bustle! - and Cosmo Canyon that capture the original feel it'd be incredible.
