I'll be honest:
I was pretty satisfied with CGL's strategy of rolling out NuSeen art by folding it into the product release cycle through the various Combat Manuals, and the 1st/2nd SW books.
Sure, I was sad to see that interrupted, regardless of the cause, but that track record gives me reasonable confidence that things will roll forward again, once new releases start showing up on shelves. (Insert positive, or negative prediction about future releases here.)
I've waited 20 years. I can wait a little longer. I agree with ActionButler: The game's playability and viability aren't really hurt by their absence.
(Also, am I the only one who would rather see TRO3039 with the new art, rather than TRO:Succession Wars?)
