As long as its coming, I'm pumped. I really enjoy some COD mixed in with some Mario, X, Zelda and Watch_Dogs.
The lack of promotion thing is baffling though, it would cost nothing extra to include the Wii U logo on the promotional material. There is definitely a financial push from somewhere, either funds from MS to imply its not available on Wii U or a lack of funds from Nintendo that Activision enjoys from the other platforms.
But again regardless, I'm just happy if its there. COD fills a genre void that Nintendo doesn't provide.
