I saw on yakyubaka about a week ago that Chunichi is thinking about/planning to have red alternate uniforms this year. The design of the red uniforms has yet to be released, but I'm behind the idea even though it's probably a little early for them to do alternates, since their new uniform set just came out last year. I'm also thankful that they settled on red, rather than yellow or green which was apparently discussed. Of course there is always the chance they will break those out in 2014.
I'm not sure when the new uni's will be released, but in the meantime I've come up with a design of what I'm hoping they will look something like.
