i though there was another patch coming for new vegas but its been awhile and they are releasing the next DLC fairly soon. unless they are planning on waiting to do i the same time as the DLC. it used to be the released them early because they had to make the game work with the DLCs or something.

Yeah, SOON

The patch is one of the reasons that OWB was pushed back to July. They want to get the patch sorted and ready before releasing it.
