Still getting updates, matchmaking is pretty much instant, and dev is still good. I think they've slowed down on content since release, but they are still doing balancing, reworks, etc while adding new content and have a roadmap and planned features floating around somewhere iirc. They've added new maps, reworked existing maps to make them more even and more fun, added new guns, balance guns when one floats up to be OP but not nerfing them into the ground (except when needed, there was an SMG that was absolutely broken at launch).
I played bf2042 for about 10 minutes before returning it, I have about 300 hours in battlebit. Graphically it's absolutely nothing special, but gameplay is very smooth, destruction is great, don't need to worry about lag or fps much because of the graphics so everyone is pretty even regardless of machine.
I do miss jets/planes from battlefield games, but that's about it tbh
