Well, the part where wizards are making a videogame and not a ttrpg is something we agree on. I just think it's not just c-suite people's ego that's on the line - the survival of the dnd branch kinda hinges on this game bringing new people in to replace their old fans. So they are incentivized to try their hardest to make something very polished and they seem to be trying.

I'm mostly basing this on info from Stephen Glicker from Roll for Combat who worked in the dev industry and is familiar with people in it. He said on stream that WotC hired a lot of very experinced (and expensive) additional developers, on top of their existing team. It would be very very dumb to spend all this money to release an unfinished product, considering that there isn't really any urgency. That said I can totally see those big wigs being this dumb.

I also am curious with how they intend to fit the whole AI DM thing into this. I agree with you that currently it can be unreliable and I doubt that it can be brought to expected quality. Personally, I think they would rather quietly abandon that idea and just make conventional videogame AI rather than risk releasing an inconsistent product. I guess we'll see.

It's possible, but I doubt that WotC would ever release it unpolished. They alienated a big part of their hardcore audience and don't seem very concerned about keeping anyone left. So it's safe to assume that they are banking on getting new players from their "VTT" videogame. And for that to happen they can't deliver something unfinished.
