Teaching children real world knowledge is something that shouldn't matter? I find that highly offensive! If a child can learn about how the real world can function from a video game then in my opinion that video game is doing something right.
If you read alot of pokedex entries you find that pokemon do infact each one another, Kabutops' pokedex entry states: A slim and fast swimmer. It slices its prey with its sharp sickles and drinks the body fluids, now if we look at this would you rather a child learn such facts from real life learning? or from a child friendly game designed in my opinion to teach people the importance of treating the animals within the world with respect and dignity and that those animals have there own cycles of lives.
Another pokedex entry this time from Glalie: Glalie has the ability to freely control ice. For example, it can instantly freeze its foe solid. After immobilizing its foe in ice, this Pokémon enjoys eating it in leisurely fashion, if a child read this it would think it's a little weird but it would not see the immediate fear because I came from a game, where as if the child were to see a real life animal slowly eating something else it would not be as interested and would initially be frightened.
Going back to the main thread topic, it is really hard to speculate on the new pokemon that are going to be introduced in this new region as we already have a large number of pokemon which have filled near enough every category within the world as to what they can be only the people at Game Freak can be smart enough to keep a trend going where they can create new pokemon within necessarily making them look like older pokemon, although in some cases such as the generic bird pokemon it is hard to do that because it is extremely difficult to make a standard bird look different in 5 different generations. The only way I see Game Freak getting around problems with repetitive pokemon would be to either bring out new evolutions for pokemon that are only a 1 stage or 2 stage pokemon or to introduce new pokemon types completely which would help with new pokemon concepts.
We have already seen five of the new pokemon to be within the new generations and if we exclude the legendaries for now you are left with the three starter pokemon, these three pokemon do look incredibly like other pokemon from previous generations and I hope that Game Freak doesn't do this with too many pokemon otherwise you could see some trouble they might get from the older and passionate players of the game. Pokemon are to be unique from any other pokemon and even though people complain about pokemon such as Trubbish stating "IT'S JUST A PILE OF TRASH, WHAT A STUPID DESIGN" infact the pokemon Trubbish is a fantastic design, Someone tell me have you seen a pokemon based on trash before? the closest you can think of it the Grimer line which is actually chemical waste, so going from that point any new pokemon which can resemble real world things like Vanillite representing Ice Cream are actually very clever ideas and again bearing in mind that pokemon is a childs game does making new pokemon like Vanillite a necessary thing, all pokemon are based of alot of real world things, Ditto looks like Playdoh, Sandile is a Crocodile, Wingull is a seagull, Murkrow is a standard Crow. So before people judge a few pokemon by what they are in real life, maybe they should think about previous generations and how close they are to real world things.
Making new and exciting pokemon in generation 6 was always going to be a difficult task for Game Freak but you need to understand the amount of talent that company has to have already made over 600+ pokemon and still keep a franchise going strong! We will have to wait and see what the future will look for pokemon and how they're are going to get around the ever shortening list of things they can base pokemon of but I don't think you can be surprised when they give you pokemon which do resemble real world things.
This post may be a little long and I appreciate anyone who takes the time to read it, for example Shawn! but I thought getting my views across may enlighten a few people who are still unsure about what the future of pokemon will bring!
Twilight Sky I think you may have derped a little in that point you're trying to make, If we take all Real world concepts out of pokemon, Gravity will be gone, time will be gone and the whole world will never exist, essentially we will be playing a black screen.
