Capcom are practically waving this one in our faces at this point.
Sly tweets and the huge success of Resident Evil 2 Remake have all but confirmed that a remake of the third game is in development.
With how similar certain aspects of Resident Evil 2 and 3 are, it would only make sense for a remake of the third game to be released fairly soon.
The similarities between the two games would also make development a lot faster than it would otherwise be. Although it's still a lot of work, it's definitely not going to take as long as Resident Evil 2 did.
We'd love to see this happen sooner rather than later to keep the momentum of the Resident Evil games at full speed.
If it isn't a remake of Resident Evil 3, then it'll be Resident Evil 8 and we'd honestly be chuffed with either result.
