I for one am enjoying this myth of 'Cut Content'. The implication being that these things were in the game until recently, but somehow removed when the reality is, game design is an iterative process and it's standard operating procedure for things to change as a project evolves. Things that might have been talked about years ago existed in possibility space, but invariably didn't pan out as the project progressed for a myriad numbrer of reasons.
Will there be updates? Absolutely. Will we get more customisation options? Undoubtedly. However right now having just released the stability patch with 1.1, and the emphasis on 1.2 being major bug fixes (including the AI which everyone goes on about )it's only after that will we start to see the QoL improvements people are after, as well as the DLC.
If you're getting antsy about these things, the best advice is to play something else for now because realistically, you're not likely to start seeing notable updates until March/April at the earliest.
Did they make a statement about AI being in 1.2? I would think they're just going to focus on getting the game back on the PSN store rather than deal with something more difficult that yields less returns. People didn't drop the game on consoles because of poor AI, it's because it can barely run in many cases.
As for cut content and iteration; this is largely true. Problem is they bragged about features months, some just weeks, ahead of release. Much of what was cut was likely due to necessity. That this game runs relatively well, outside of being broken and unfinished, is still a technical achievement. There is some very ambitious stuff here. Hundreds of detailed NPCs, cars, sidewalks littered with refuse, dozens of area lights and thousands of decals, volumetric lighting with ray marched clouds on screen and then topping this off with an underground railroad and elevated transit that's believably populated and interactive? That's a tall order. I'd bet they tried and couldn't get it to work. What we have right now is literally the best they could do.
