It's a bummer as I was looking forward for COD on the go, but realistically speaking, it shouldn't come as surprise. They've been burnt by the sales on the Nintendo systems in the past, so they're taking wait and see approach. If the Switch's sales will stay on the current level and there's money to make on that system, those big franchises will come, regardless the technological disadvantage. All Nintendo needs to do now, is to keep pumping those big in house titles, to keep the momentum going and by the looks of it, this is what they're doing.
Edit
The big testimony of how well the 3rd party games can potentially sell on the Switch, will come with the Skyrim and FIFA. I'm convinced that Skyrim will perform well, but despite what people think, FIFA sales will be the best indicator of things to come. It's insanely popular in Europe, where for Nintendo, European market is nowhere near as big as American and FIFA/sports gamers in general, are the target audience for FPS developers. If it can perform well on such niche, like for Nintendo, market, it will perform great with other, even more popular, titles.
