Pokemon has a very big focus on the RPG element, and while we forget that a lot, it is a turn based RPG. I mean, sure some pokemon spin-offs are fun, but they don't have the cult following the main series has.
So everytime I see "We need a Skyrim-like Pokemone game!" I cringe a little. I don't think we need anything like that. Not in the main series. The newer pokemon games XY, ORAS has a great deal of open-worldness already, and changing the entire formula will just result in a disaster.
