When they get problems it costs time(money) to fix them and therefore they need to get permission from the publisher(people funding the game development) to do these fixes. This is mainly determined by how much money it will cost. Money spent paying programmers to fix bugs and money lost on lack of progress made. If the problem is only semi important but would take many programmers month/s to fix...they might not get permission to do it( other factors such as project management and time constraints will also play into this).
For them to get permission to make a patch, it largely comes down to how much money it will cost them to make (as stated above, time spent on the fix and time lost not working on next project or dlc), as opposed to how much money will they lose from loss of sales(short term and long term). Since most of these bugs do not keep you from playing the game, they probably wont be fixed. Some of the ones that keep missions from triggering might get fixed, they might not... since we didnt code it, we dont know how deep these problems lie. Game crashing bugs are annoying, but unless its literally happening every 2 hours, it probably wont be fixed... we'll probably just be warned to save on multiple slots and to save often. Terrain clipping bugs (like rad scorps being stuck in the ground) will most likely not be fixed. Anything that has to do with companions will probably not get fixed, since they are not needed to complete the game.
Main mission bugs that keep you from completing the game have the best chance of being fixed. I would guess that the secondary mission trigger problems will be next (e.g. i cant do veronica's side mission "I could make you care" because she wont trigger her conversations that lead into it).
All in all, i wouldnt expect to see any patches anytime soon. They have to determine where the bug is, how much work it will take to fix it and if they get the ok to fix it they have to test it before the patch goes live. The most we can do is politely list the bugs we find and hope they can fix the worst ones as soon as possible.
BTW- ive noticed that the longer a play session lasts, the worse the loading and crashing gets ( im guessing its a memory leak). If you notice that its taking longer than normal to load an area, save and reboot the game (be safe and turn the xbox off and back on). Ive noticed improved load times( they go back to the normal really long load times, as opposed to the obscenely long load times) and my game rarely crashes now.
