Nope, Nisemonogatari is over. They've already started work on Kizumonogatari.
The order for the light novels, and presumably any anime they continue to make, will be something like this:
Kizumonogatari (in production) - Prequel, when Koyomi meets Kiss-shot Acerola-orion Heart-under-blade. (AKA Oshino Shinobu in Bakemonogatari and beyond) Pretty much all the titles in the series are a play on words, in a manner of speaking. Often Japanese words have more than one meaning in English, and Nisio Isin tries to play on that as much as possible. I mean, the guys name is a palindrome, for crying out loud.
Translation: kizumono - defective, or unvirtuous girl, monogatari - story
Chapters: 18. This lends credence to the idea that Kizumono will likely be an OVA.
Bakemonogatari (done) - A brief look at most of the girls.
Translation: bakemono - ghost, monster
Chapters: 41 between volumes 1 and 2. This took 15 episodes, a normal season has 12.
Nisemonogatari (done) - Karen and Tsukihi.
Translation: nisemono - impostor, fake
Chapters: 35 between volumes 1 and 2. This took 11 episodes.
next is Nekomonogatari (Black) and Nekomonigatari (White) - Tsubasa
Translation: neko - cat
Chapters: 79 between black and white volumes. I have no idea how they plan to do this in a season without cutting a helluva lot. Unless they want to make it 2 seasons.
Kabukimonogatari - Mayoi
Translation: kabuki - gate, drama
Chapters: 30
Hanamonogatari - Suruga
Translation: hana - flower, nose, end
Chapters: 32
Otorimonogatari - Nadeko
Translation: otori - decoy, lure (Yeah, Hitagi does NOT like Nadeko.)
Chapters: 24
Onimonogatari - Shinobu
Translation: oni - demon
Chapters: 33
Koimonogatari - Hitagi
Translation: koi - means a lot of things, but since this book revolves around Hitagi, it most likely means 'love, passion'
Chapters: 39
There are also three more light novels that have not been published yet, but have been confirmed. Rumor has it that they take place after Koyomi has graduated from high school.
Tsukimonogatari - Yotsugi (the shikigami that shinobu fought at the end of nisemonogatari)
Translation: tsukimono - attendant, accessory, devil possession
Owarimonogatari - No idea who this one is about, but it's titled 'Ougi Dark', which roughly translates into 'Dark Secrets' or 'Dark Mysteries'
Translation: owari - the end
Zokuowarimonogatari - This one supposedly focuses on Koyomi again.
Translation: zoku - race, group (combining zoku with owari can potentially either mean a race to the end, or the end of their group? just speculation at this point)
