Actually in the one or two months after Reforged released, they added Single Player back into the game. There was a time when the developers were making changes.
Anybody I ever heard of who worked within Blizzard on Warcraft III Reforged no longer works on the project at this point, and the ones I messaged personally online enough to ask about their lives no longer work at the Activision Blizzard company.
My understanding as a Warcraft III fan was that the people who wrote the update about ladders and profiles mentioned above by HyperTurtle, all those people, were either sacked or told to do something else more profitable with their time. I would not personally assume that the stuff in those posts was ever actually going to happen, but apparently some of the die-hards in this forum would say that was pessimistic.
One of the ways I look at it is that a lot of players talk about “Refunding the Reforged” and they really believe that by doing that, they exercised their rights to demand a better game, so that they could buy it again if Activision Blizzard reworked the project into “the experience players wanted”.
However, I think that this financially real sort of public statement that players wanted to make was probably actually falling on deaf ears who could “hear only the money”, you might say. In other words, to an apathetical leader who can shift to be manager of any game he wants, the solution to a game whose fanbase thinks it’s OK for everyone to refund the game… is to shift over to be a manager of any other game. Literally anything else is better than a product where selling it to people might actually be them lying to you and you have to have cash on hand to pay them back later. I think that’s just how it is. I’m guessing even if I was a manager at this company, I would have to support the internal pressures from above not to touch Warcraft 3 even with a 20 ft pole. I just can’t see it any other way, really, and maybe this is my tremendous bias or maybe this is just what I see as true.
So, you asked for insider information instead of all this heresay from a random guy like me, but what I’m trying to tell you is that I think there might not be any insiders anymore. There might not be any information anymore. Maybe it’s over.
Edit: So, in hopes of being able to continue my hobby of modding Warcraft III despite the above, you might say… I have set about trying to rewrite the entire Warcraft III game as a separate program game engine not affiliated with Blizzard Entertainment, where the War3 artwork will just be one set of artwork possibilities you could input to my toy game engine. So far, I am able to play Warchasers map on this toy engine, with some limitations such as no hero skills. So, if I get far enough in my engine to Reforge it, maybe that can be the future of what you wanted.
Obviously this video is not 1:1 with how the Warchasers map is meant to play, and I gave myself a customized hero with ridiculously increased attack speed. The reason for this change was that on my game engine, agility bonus to attack speed is not programmed in yet. So, I wanted to put in an attack speed that would still be good even later in the game if I get that far.
Also, the moon key did not disappear when I used it to open a door. This was because I never programmed in the RemoveItem function. That’s also why destroyed items leave their shadows on the ground forever.
