Square Enix and Studio Bentstuff have a couple of Ultimania guide books on the way for Final Fantasy XIII-2.
The 800 page Final Fantasy Type-0 Ultimania guide, released yesterday, has an advertisement for the XIII-2 guides. Square Enix will release separate Scenario Ultimania and Battle Ultimania guides in late January.
The advertisement does not list a page count or price.
The original XIII also saw Battle and Scenario Ultimania guides released a month after release. These were respectively 543 and 511 pages. The game also later saw a 511 page "Omega" Ultimania book with artwork and interviews.
