I merged the two threads on this subject.
There is actually some news on this this week. David Duchovny has been interviewed here: IESB.net - Independent Entertainment News - X-Files 2 Negotiations Wrap This Week Says Duchovny!
This has been reported at both Hailing Frequencies and SciFi Wire.
Apparently, the contracts are going to be signed this week. EW reports that Gillian Anderson's manager Connie Freiberg says, ''there's no obstacles other than the delivery of a great script.'' We Want to Believe | The X-Files | Movie News | Movies | Entertainment Weekly
David Duchovny says that there is a story board at least. It is going to be more Horror than SciFi. It will only have the core characters, and no Robert Patrick.
I'd take this with a pinch of salt though - just look at the earliest posts in this thread!
