I actually think that knowing the route they are taking by February is extremely optimistic. I think February will mark the point that CDPR has to actually tell us what they can and cannot implement based off the amount of performance that they can coax out of the engine and the hardware configurations that are being ran, it's a sad fact that what I consider average performance hardware wise is out of the reach of 95%+ of PC gamers and all current and next gen console gamers. IF they considerably downgrade the graphical fidelity of the game to be at the optimized performance range of the 1XXX series, they may be able to re-implement approximately 50% of the cut content. We likely won't be receiving things like wall running/climbing and the fashion system seems like it will be too much of a performance sink to implement.
That being said I expect the AI issues to be somewhat resolved in Jan/Feb for most players except those on cards weaker than the 1080, the reason for this is the weaker cards are off-loading graphics processing to the CPU for certain things which I believe may be causing some of the AI quirkiness, as I haven't seen those issues myself, the AI in my game isn't as bad as some have shown theirs to be on youtube, as I regularly get one shot-through walls by guys with tech rifles on Very Hard their headshot ability is uncanny as fuck, they use cover semi-intelligently and while they don't make the best tactical decisions neither are they the worst I have ever seen though normal sniper AI needs some work, and outside of Netrunners who only apparently have 2-3 quick hack choices across all levels.
I expect we will see talks of the addition of factions through free-DLC size additions come 2Q21, and a continuation of V's story come 4Q21 in the form of a paid DLC to expand (in this context I mean fill in) the game world. Between those two points, I expect a great deal of AI balancing, weapons/gear balancing, and other additions that were promised as part of the games lunch but didn't ship such as apartments, races, possibly an increase to persistent NPC's and decrease of the number of procedurally generate NPC's. Transitioning away from procedurally generated NPC's is necessary to establish actual Day/Night cycles and routines for the various NPCs. At some point I expect more romance options to become available as well. I also expect to see significant changes in the Perk tree's as there are too many percent bonuses, not enough flat bonuses, and too many combat oriented perks and not enough social perks, ideally Body, Intelligence, Technical Expertise and Cool will have their own social interaction options expanded and perks added to their trees to represent those social interaction opportunities.
The game as currently optimized is optimized for the 20XX series cards and their AMD equivalents. With the release of the 30XX series Nvidia moved the performance divide again. My 2080 Super, in spite of being considered a high range card a year ago, is now considered a mid-range model, and the former middle tier the 1XXX series are now at the lower end of their shelf lives. A 1080Ti is no longer considered the beast of a card that it was even three years ago. Fortunately for PC gamers, we have hit the overhead value on production lines for Moore's Law which means that the release of STRONGER cards is likely to slow, allowing driver support to finally catch up with the rat-race that has been the break-neck race to stronger cards from a sheer calculation standpoint. Instead they will focus on broadening the scope of cards, such as boosting concurrent performance of both rasterization and ray-tracing performance when used side-by-side.
TL;DR: What we get feature wise is very much dependent on code streamlining based off of the compromise of graphical fidelity due to the complexity of Night City as it exists in relation to lighting and shadow geometry, and to a lesser extent texture quality.
