I was able to pick up the new MagicBands today and get some high quality pictures. The bands are available throughout the parks, but I picked mine up at the Nikon Camera Center right inside Epcot. The Americana Mickey is Limited Release and the Grumpy is Open Edition.
Americana Mickey is the first Limited Release band to be released within either of the four parks at Walt Disney World in quite a while. Not counting the runDisney bands, which were released at the ESPN complex, the last Limited Release band released was back in late 2014 for the New Years 2015 Mickey MagicBand. This band does come in standard hanger packaging with the gray Limited Release sticker on it.
