A scan of the upcoming issue of Monthly Comic Zenon magazine, to be released on March 25, revealed that manga Wakako-Zake will be adapted into a TV anime series. The manga also received a live-action TV drama adaptation last year.
Chie Shinkyu started Wakako-Zake in July 2011, and the seinen manga is still ongoing. It is serialized in Monthly Comic Zenon and published under Tokuma Shoten. The fourth volume of the manga ranked 41st in its first week on Oricon's weekly manga chart last December.

"In the past few months since we met, I've shared many memories with Nagato. Though I've also shared memories with Haruhi, Asahina-san and Koizumi, I found that I've experienced more events with Nagato in particular. In fact, every situation seems to involve her. I might as well mention this, she's probably the only person to cause the bell within me to shake the most vigorously..." ~ Kyon, TMOSH
I've seen raw of this available now (live-action drama, I think) on streaming site. It's just my wild guess, but I'm guessing (and hoping) it will be one of the short anime to be aired in Super Ultra Anime Time airing in Summer or beyond that.
