Well, I'm playing on the base PS4 and after patch 1.1, I've noticed a definite improvement in the frame rates. The game runs more smoothly right now which is great. I don't find the need to tip toe in dense areas anymore, so yea.
Apart from that, I find that when I'm playing for long periods of time, my game doesn't crash anymore like it use to. So that's a bit of a plus for me.
With regards to the bugs/glitches & so forth; I've been fortunate enough not to have experienced them with such regularity like how, unfortunately, so many of others have. But knowing that this is going to be CDPR's biggest priority in patch 1.2, I'm expecting quite a bit of these to be sorted out. Yes, I do feel that by trying to fix the current bugs, some others may pop up but at least the total bugs in the game will be reduced, so that'll be good. If there are any major game breaking ones, I think CDPR will act quickly to resolve them like they did with the Takemura call one in hotfix 1.11.
So, in addition to the above, I'm expecting patch 1.2 to improve the resolution for us base console players a bit. To be honest, I'm accepting the way the game looks right now. I don't find it to be that big a deal. But you know what...after looking at the gorgeous PC version, I can't help but to expect a bit more from our base console versions after patch 1.2. I don't know whether this will be possible (base consoles can only do so much, you know) but if it happens, I will be a very happy gamer. This game was meant to pop with all its vibrant colors so I'm expecting it to look, not as good as the PC version obviously, but at least a bit better than what I'm seeing right now on my slim baby.
