so if the writer's strike is resolved, will JMS be working on the Lost Tales?
Perhaps. Last we heard, WB was just beginning the process of commissioning more. There are at least two other projects that were just about to start negotiations when the strike fell, though.
on a side note, does that mean that JMS is currently writing for the script book during the writers' strike?
Yes, of course. The strike only has to do with writing for TV or movies under contract
with the struck companies. He can write speculative scripts that aren't under contract or for any other medium he likes.
