I'm hoping Topps doesn't do anything extreme to change the Postcard series, like they've done with ANS10. I would hate to be ambivalent about a new postcard set release.......
too late, the PC's are already there.
I would argue it's the PC's that brought us to having two versions of ANS10, by offering those 'collector edition' postcard sets with the sketches, autographs, alternate bonus cards, etc. - that all sell out within hours or days, as well as the standard postcard sets. It's worked for the PC's, so why not try it with ANS?
And the PC's keep evolving too, like with the last Halloween set - shaped cards and even different versions of the same base card.
I say expect more of the same from both series.
