There will be, but how much it fixes who knows. Visual bugs I can handle, though not if they are just constantly happening. The occasional T pose, missing head/clothes, floating gun I can deal with mostly and forget. I'd rather the bugs like mixing audio, audio not triggering in converstations, sometimes even missions not working are mostly fixed. The one review I watched said floating weapons were a big problem and consistent but after a patch sometime during their review the problem went away, so can only hope for fixes like that. I think the funniest bug the one reviewer mentioned was the famale Vs top clothing randomly disappearing during scenes, leaving you topless until you went back to first person.
At least it seems like gunplay is good, seems eveyrone says melee feels somewhat off and the rest of the game(story, quests, character depth(not looks) and world) is amazing. Just mainly a lot of technical(visual/audio) bugs. I can only hope a decent amount of fixes are done so that these glitches are few and far between, especially as its been delayed enough for these thigns to be worked out. I don't expect zero bugs, especially in this type of game.
