The producer of the series Castlevania: Lords of Shadow, Dave Cox, used the framework of the GameCom 2012 to comment on his twitter some details of the upcoming Castlevania: Lords of Shadow - Mirror of Fate for Nintendo 3DS, a game that will finally be released in following year. However, he has used his social networking account just to talk about Mirror of Fate, and announced the development of a PC version of Lords of Shadow 2. Answers come fast, because then confirm the PC version, it said that there will be the title for the Wii U, offering a reasonable response from the business perspective:
How many people have a Wii U? Zero. How many people have a PC? A lot. Never say never to the Wii U, but it is difficult to do so - Dave Cox
Thus, Castlevania: Lords of Shadow 2 will not be on the Wii U because it is a new console, and its installed base is very small in its first months. From the standpoint of a business is a very understandable reason. See for yourself at this link.
