To be fair they've already faced backlash and don't seem to care, it's resonating with an audience and selling well regardless.
At this point they'd have to mess up something
really huge to actually face more substantial backlash than a few angry voices on internet forums. And all things considered, if that core audience was already fine with all the shenanigans that took place in the finale of Part 1, I don't think anything could throw them off.
Personally I've embraced the "Remake" series as something that isn't literally trying to retell anything, and honestly I think I prefer that to a 1:1 recreation of a game I've already played. It may well end up being worse but at least it's interesting.
Fan modders have basically got me covered when it comes to modernizing the original release.
