Even with a T.V. deal, it's not a smart idea to do singles. Fans have made it pretty clear that they want 13-26 episode boxsets. All you need to do is release a boxset after 13-26 episodes have aired on T.V.
Anyway it's true, but even so I think this is only temporary. Anime has been on American T.V. since the beginning, and it's now more popular than ever, I don't see why it can't make great presence again on mainstream networks in the near future.
