I thought WotC has said the revised core books had to be staggered due to printing logistics? Also I don't think there's going to be much to convert between 2014 and 2024.
You know, I couldn't put my finger on why I didn't really dig Golden Vault. I think you nailed it though. I don't think I really liked it didn't have a base setting.
I wouldn't mind if they released the old books again like they did in the between times (between 4e and 5e). I wasn't able to purchase those at the time and remember thinking they looked nice.
I'm not sure about that but over the past 6 or so months it seems he pivoted somewhat from D&D the game to sensational D&D is doomed type videos. Ive noticed several D&D YouTubers I generally liked watching do this.
I run my games in FR but it's kinda mine own version. None of my players keep up with what has happened so I can change it however I need to. One day I'll jump to my own home brew world.
4e Essentials felt more like an attempt to do some sort of course correction. 3.5 can be perceived as a cash grab. The total rules update for 3.0 could have been done slowly over the life of the edition I would think. 3e seem like it had legs.
