2ch where fans have discovered listings on Amazon.com for two interesting Blu-Ray/DVD releases: Kizumonogatari and Nisemonogatari. Sound familiar? They're the titles of the prequel and sequel, respectively, for Bakemonogatari, NisiOisiN's light novel series, which was turned into a rather popular anime in the summer '09 anime season.
So, what does this mean? Well, it's entirely possible-- perhaps even likely, given the popularity of the Bakemonogatari anime --that Kizumonogatari and Nisemonogatari are getting their own OVAs (TV series is also possible, but somehow I feel like that wouldn't be up on Amazon this early).
On the other hand, Amazon is rife with strange and/or erroneous listings, so for now we'll call this a "rumor," and I'll give it a 7.5 on the likelihood scale (1 being "pigs flying" and 10 being "George Lucas finds another way to !@#% over classic Star Wars fans").
For the record: like Bakemono is monster and monogatari is story, so Kizumono is a defective or damaged item (or, colloquially, a deflowered woman), and Nisemono is a fake or counterfeit.
This is still a rumor, but in the event that it turns out true, might I acquire a "hell yes," please?
