As much as I would like to watch season 2, I highly doubt it'll happen. The likeliness of S2 coming depends on many factor including the manga sale volume and how much sale the anime pushed in as well as media profits (DVD, OSTs.. etc). However, the total profit this series pulled in Japan wasn't as hopeful the studio wanted and a S2 is very unlikely.
This series had a fresh idea (even though still based on card games) it was more down to earth, the animation was very well done and like I said, as much as I want to hear an official announcement that a S2 will be released in a few years time, I wouldn't hold my breath and get my hopes up. I guess for us at least we still have the manga to pull us through and "hopefully".. they get to finish that at the very least.
Merry early Christmas or Happy early birthday everyone. According to multiple sources, Chihayafuru has been announced it'll be renewed for a second season. Exactly when it'll be aired is still unknown.
