I think you are referring to 1st Printing rather than edition per se.
While some game companies recently have decided to revise their books after every printing (Godlike comes to mind as an example), I haven't heard that Decipher is going to do that. I think its safe to say that there will not be a new edition of CODATrek for at least a couple of years, if even that soon. Unless I am missing some word from Decipher?
As for the Enterprise sourcebook - Don has said the information therein would eventually trickle down to future supplements but I seriously doubt that it will appear in future printings. Possibly future editions but like I said, thats probably a long time away.
I love deadlines - I love the whooshing noise they make as they go by
