Rain Games is advertising that they will be a part of the Nintendo booth at Gamescom which is August 17-21. They will be porting one of their recent games World to the West, and it will be available for preview during the show.
They are also not leaving out the option to also port this same title to the Nintendo NX. Only time will tell as we know next to nothing concrete about the Nintendo NX. All we really know about the NX is that it will be available in March of 2017, and a few games that will be released on it. Will World to the West be a launch title?
