Something tells me that when LFL used the words "demand will keep them in print" with regards to Legends, they meant to imply that only Legends products which continue to sell really well will continue to be sold at all. And when the new movies, books, video games, etc. get off the ground, Legends will become less and less in line with the canon universe and sales will drop precipitously. Basically, I think the whole "Legends" brand is just a ploy to placate EU fans for a few years until the majority of them have moved on and embraced the new timeline. By then, Legends will most likely all be defunct and no longer sold under any label. It's difficult to underestimate the degree to which the new movies will propel the fan base in their direction. As well as the degree to which a lack of new material will render the Legends timeline obsolete.
