ReynardFox: This "it's hard to program for" is an excuse, and a number of talented devs like Shin'en and Frozenbyte call out devs on it. The Wii U is actually really easy to program for, and quite simple to port PC code over to (Did you know, on a whim Crytek changed a few lines of code and shoved Crysis 3 onto Wii U and the damn thing ran really well? Naturally EA said no anyway because spite) and Castlevania games have a history of selling well on Nintendo platforms. It feels dismissive to not include the platform where the series earned most of it's legacy.
It's not hard to program for in the difficult sense. I'm sure the the Wii U is easy to program for. It's just extremely easy to port via the same architecture and those other systems are near-guaranteed to have good sales. I love the Wii U, but even I have to wonder if it will be around in a meaningful way in 2017, given the state of things. I'm sure that they would love to have it on a Nintendo platform, but what he said does make a level of sense. Now that they have such amazing funding, however. I certainly feel that they should do a Nintendo version.
P.S. - Could you link that article about Crysis 3 and the Wii U? That sounds interesting and I would love to read it. :)
