According to a quick post by Bethesda's Matt Grandstaff on the company's blog, Fallout: New Vegas will be receiving a second "comprehensive" patch on the PC, Xbox 360, and PlayStation 3 soon. In fact, it sounds like we'll be seeing it within the next couple of days:
We wanted to give you guys a heads-up regarding the latest progress on Fallout: New Vegas updates.
We've come up with solutions for the Xbox 360 save issue folks are reporting, along with a number of other issues being reported. We're currently running final testing and certification on a comprehensive patch for all three platforms (PC, Xbox 360 and PlayStation 3), so we'll have something available in the coming weeks. When we have more details, we'll let you know.
In the meantime, an incremental update for PC should be going up by early next week that will fix the save corruption issues and problems with companions, as well as improve performance for NVIDIA users and resolve some issues reported with Havok.
