I'd like to remind people not to get their hopes up too much for the Rayman 3 remaster: expect them to do the bare minimum and be (un?)pleasantly surprised if it's anything more than that.
The
original rumor about this remaster included it in a larger amount of Ubisoft remasters (6!) as part of a Nintendo 3rd party Switch 1 support initiative.
Considering the amount of games being remastered, it seems unlikely that they will do anything more than a simple port for any of the games listed.
If the rumor is to be believed at all, the situation here sounds like a last-minute effort to keep supporting the Switch 1, rather than BG&E's 20th Anniversary Edition, which was a project started years before its release in collaboration between Ubisoft & Virtuos. I think major graphics overhauls, soundtrack redos and more are out of the question here (personally, I'm more than OK with this, the old game is perfectly fine and the BGE remaster was a huge downgrade from the original). Unfortunately I don't even think we'll get anything like BG&E's Anniversary Gallery. I'll be happy if I'm wrong though.
Of course it could turn out that this rumor was false, and nothing is getting remastered.
As for Christophe Héral's "multiple Rayman games" concert description, keep in mind this wasn't written by him. It was written by some random person who worked on the website of No Limit Festival - hardly a reliable source, not even for whether he is currently working on
any Rayman project. (Of course he'll continue to compose for Rayman if they ask him, and he is the obvious choice for the composer of a new game, but I'm not really sure if they will ask him for a remake.) I'll believe it when I hear it.
It's more worth reporting that this concert will include an orchestral performance of Rayman music on March 23rd! I'll give it a listen if they publish a recording later on.
I apologize if this post comes across as negative, but I felt like it needed to be said. In these past few years I've seen so many times that people get their hopes up without thinking, only to be extremely disappointed when whatever they dreamed of doesn't happen.
