There has been no word of a Gen VI in Pokemon, and there won't likely be a Gen VI for a few years. There are rumors that the next games that are going to be released, (more than likely at least,) are going to be Gen III remakes on the 3DS, and even though this has yet to be confirmed, I'm almost positive that its remakes will be made very soon because they are the only games that don't have remakes on the DS, (Gen I is technically remade in HG / SS.) And you're guess is as good as mine when it comes to the design and the names of the newer games since they [probably] won't be released for awhile.
