Although it's not stated, in a magazine it is expected that Kingdom Hearts II Final Mix, and Final Fantasy XIII to make an appearance. However with Nomura's 'suprise' for Jump Festa, that might just raise the chances for this.
Also as quoted from www.kh-2.net
On official KH mangaka Shiro Amano's blog, there's a post about the KH2 book and a story concerning the up-coming calendar.
â€¢ The schedule for the KH2 book is in December.
â€¢ Often, we should be able to see what the notification of what volume number, the book is. It could be numbered, 'volume one'.
According to this blog's poster, there are rumors of a new comic illustration that was already drawn and written along with Jiminy's memo prior to the KH calendar.
I just sorta hope they don't get mad at me for copying and pasting their exact translation of it.
However thank you KH-2.net For the new Calender Information, as well as the information on Jump Festa!
Also thank FF&KH Blog for informing all the KH Fans with the JF, and Shiro Amano for the information on the KH Calender
