Bethesda's Pete Hines appeared on the most recent episode of the Nintendo Power podcast to talk about the various titles they're bringing to the Switch. At the 39:15 mark in the discussion, Pete has this to say.

Who knows, maybe some more surprises for Nintendo fans on the way.

Now I don't think you become the Vice President of PR and marketing at Bethesda Softworks without knowing a thing or two about what's going on behind-the-scenes. I'd say this tease is less 'if' and more 'when.'

Thanks to Dondom95 for the heads up!
