I'm sure there is enough interest in them printing non-limited gold arcanes but that won't happen.
Are you sure they could? I thought they said the destroyed the plates or something? and do we really want gold arcanes to be common? and not rare at all? all the people who spent a lot would feel bad.
It was more of a hyperbole and not meant to be taken literally.
A non-limited Gold Arcane deck is not a new deck or even a new color - it's the same deck as the present Gold Arcane, so no, they wouldn't do that, and there's a few thousand people who would agree that it's not a good idea, all of which own the Gold Arcane.
They've said straight-up that the Red Artifice would never appear in a version 2 design, so as to not dilute the value of the version 1 deck for the people who own it.
But take their newest deck release, the "Artifice: Edition Purple" as they're calling it. The idea for that came from them batting around ideas for what would be the next Artifice deck on their Facebook page. Borderless wasn't even a given option (they were just inquiring about colors), but people were plugging it in at a rate of about 1 in 5. I found it a little bizarre that they took this to be a customer mandate, when it was an opinion expressed by only 20% of the respondents, but they thought it noteworthy simply because it wasn't a given option in the choices.
So yes, if enough people (waving enough cash in front of their faces) request a particular deck, such as a Red Arcane, there's a really good chance they'll make it, even if it's not a majority consensus - it just has to be enough to appear profitable.
