fake, one book is named after Sasuke (thunder) and the other after Naruto (wind), it doesn't mean it's gonna be some moe stuff but most probably about their relationships and what they did after the war before Sasuke left the village again or more interesting, flashback scenes!!!
it's like the 2 bonus pages from the last volume, i'm pretty sure it's gonna be their family portrait since the naruhina date is on the special volume about Naruto and Hinata.
