MGM has been reported - see the links in this post
for further information. But I too believe that MGM was either up for sale, or close to being put on the market recently. I don't know if their situation has changed, but it's worth noting Die Another Day was a co-production with Fox, and time's must be hard if you're willing to share income on your biggest money maker.
As for Universal, David's suggestion (or maybe hard information) makes sense from a business standpoint, but I have little time for most "business logic" - holding off on products (and thus reducing income) while your parent company is bleeding money (mainly from write-offs and interest payments) sounds OK in the short term, but should the negotiations take longer is it really in Vivendi-Universal's interests?
It seems to me that Universal has been holding off on a lot of products for the past few years, and has never been able to run at it's full earning potential.
