The game is supposedly being made by Virtuos Studios. According to the early YouTube videos I watched, Virtuos has little experience making games outside of port jobs.
The only real confirmation we have for this game are leaked internal documents from the FTC vs. Microsoft lawsuit. ZeniMax probably added the remake to their release schedule to make Bethesda a more attractive acquisition target for Microsoft. To be honest, I don't think ZeniMax ever intended to make the game, if they did we would have had an announcement from Bethesda a long time ago.
If this game is made, I think it will not be all that successful. It will probably not be fully moddable and any changes they make have a chance of alienating long time fans and if they make too many changes it will not feel like the original at all.
On top of that, the game itself may not be very good. This game is not a port, and the studio supposedly behind it has little experience making full games. I've read YouTube comments complaining about bugs in the original game, but the remake could have its own problems.
I don't know if this game is real or not, but I will remain highly skeptical until there is an official announcement or someone leaks some gameplay footage, because still images are not going to do it for me.
If the leaks turn out to be fake, a lot of gaming YouTubers who you would think would know better than to run off with a bunch of unsubstantiated rumors as fact are going to have major egg on their faces.
