That's the discography, but it seems like they have a new single according to the official site:
ニ団ニ但ツー窶ーテッツ湘ェナ?ツョ窶牢ナ津?窶凖ィSingle窶敖ュ窶昶??!
窶ーテッツ湘ェナ津?窶凖ィ SINGLE
窶「窶ヲ窶捏窶堙??「窶ヲツ青カ
^Whatever that means
All i can read is tour in katakana (well, that and the hiragana "to" in the last line, but that doesn't help much), and the rest I haven't a clue.
ETA: I think that they have a new single that is available at their lives for the upcoming tour and it contains two songs called 窶「窶ヲ窶捏 and 窶「窶ヲツ青カ.
