Open illustrator. Click back design shape. Select red. Sell thousands. Nice business model.
We KNOW this, bro. It seems clear, as indicated by Legacy, that the second color was intended from the beginning. E just opted to release them at separate times, perhaps with the idea of making the reds be a rare deck to replace their dwindling stock of rares. BG1E is already an "endangered species" now, since it's been removed from regular gift tiers - or does E even still have gift tiers anymore?
The deck looks great so far. I can't wait to see more, especially the court cards.
Just out of curiosity, if this is the red version of the Madison Rounders, what makes you think it would have different courts? 
I thought if he changed the color of the back design, he might also change the color of the court cards. It's probably just me, but a red court card with a red back design doesn't sit right with me. You know, all you have to do is open illustrator, click the desired card. change the color, and sell thousands. 
Hmm, that statement looks awfully FAMILIAR...
It's rare that someone changes the court colors to match a different color of the same design. It makes the deck less convenient for games - players like different backs but the same faces from deck to deck in an all-night neighborhood poker game.
It's one thing if a company builds its reputation by recycling the same designs for months or even years, doing little more than tweaking the color scheme.
It's a different thing if a company's releasing a few colors of the same deck at once, or even over a short time, particularly if there's a demand for it. Only the dumbest of business people ignore their customers' desires. It's why we have Ornate decks in four colors now instead of only two, why there's so many different Crown deck colors, why Bee Stingers are black and red, etc. As I said above, it's clear they intended two colors all along.
These decks take time to design and make - you don't honestly think that they made the blacks, then did this afterwards as an afterthought or a reply to customer requests or something, do you? If Daniel Madison has them in his hands already, odds are they were printed weeks if not months ago. I'm still seeing new releases with AoS codes indicating a print date in late 2012 - a prime example being the new Erdnase 216 Squeezers, which were printed on the next-to-last week of last year. (Yes, it's odd for custom releases to have an AoS code, but those do.)
