A list of things to be patched in the future would be really handy. I definitely won't play the game until AI personalities are in as my first playthrough will be solo, but I would assume Larian would update us about this stuff at release.
Fortunately I'm the patient type (well fortunately for me) and I don't mind waiting however long it takes for the game to get all the features (assuming it doesn't take Duke Nukem Forever long or worse Grimoire amounts of time ;-) I'm assuming it'll be all good (and tuned from post-release patching) in a couple of months or three.
I tend to think it's best to wait for a few patches for all games (why rush to have a sub-optimal experience?) though I'll buy games at full-price for companies I want to support.
Actually, what is it about playing games at release that people go so bananas for anyway? Folks even preload games so they can start playing immediately. What's up with that?
