Am I correct that to date there has been a single (1st.) printing of the game through GMT, and the reprint is on the P500? Or is there already a GMT 2nd. Ed.? Or is the 2nd. Ed. a rulebook and card update without a printed presence?
To date only the 1st Edition (Deluxe) has been printed.
The 2nd Edition (Deluxe) is on the P500 still, and is the complete game (same as 1st Edition), but features the changes Carl made to the rulebook and cards.
If you own the 1st Edition and don't want to buy a new copy (since not much will change really), you can still upgrade by downloading and printing the new rulebook, and ordering the new set of cards (or make do with your old ones).
The link Carl posted up top is to order the updated set of cards that will be included with the 2nd Edition printing.
Edited for clarity.
