There's no reason why Pokemon has to be turn based. It's world lends itself perfectly to hack and slash gameplay.

EDIT: Ninja'd hard.

You definitely mentioned MMO as well as other genres in your OP and that's true that you never mentioned GF, but the same goes. I never mentioned it replacing the core series, though; just the idea on it's own it is not a good look for Pokémon.

Nope. Just Hack and Slash. Never mentioned MMOs at all. Everyone else did. Read again.

How is the idea of a bigger and better Pokemon that respects it's core principals of the franchise not a good look?

I agree, and especially because I've been playing more MMO games lately (FF14 and best of all, SWTOR). SWTOR's combat might not be the best fit for a MMO Pokémon game, but I think it wouldn't be too far off. The thing you said about no interaction with other players except battles and stuff wouldn't I agree with, both PVE and PVP would need to be satisfactory.

But with Nintendo's current online strategy (which is getting a lot better, but still not there) I would rather wait ten years at least before they start making it. Could easily overtake the throne of most subscribed game (and to all subscription haters, how could they really finance it otherwise? Subscription models are just fine in MMOs).

An MMOish Pokemon is what you are making it sound like, and to that I say no thanks. Pokemon is perfect with the turn-based combat and strategy, and the contained worlds.

Also, this wouldn't be overtaking the core Pokémon games (FF14 doesn't overtake the main single player ff games, and SWTOR will not be hurting Episode 7 ticket sales or Battlefront III). Just a huge supplemental game, and also an invitation to other hardcore MMO players who might like the universe of Pokémon but not the battle system.

Because your better does not equate to everyone's definition of better. I've read your OP and I do not like many of your ideas. That's not to say I don't think Nintendo should do something new with Pokémon, because they should. I didn't like X/Y and I've said it many times. I think largely they just need to up the difficulty, or at least give us a difficulty toggle before we start a new game. The regions could be expanded, but that's not necessary if the region is just designed well and the story is beefed up. (And yeah, I know you aren't really talking core here, but I am.)

Who would you want developing your dream Pokémon?

Gamefreak has too much control over the franchise and they clearly have no interest in developing a mainline Pokemon for consoles. I'm sure Nintendo has tried to convince them many times but they're content with handhelds. It's a shame because Pokemon on WiiU could be a gamechanger for Nintendo.

The game I describe is not an MMO, so none of what you said applies to my concept.

No it's not. Like I said, Destiny, Watch Dogs, Journey, The Division, and Dark Souls are all not MMOs. That is the kind of online shared world I am talking about.

Pokemon is not perfect with turn based combat. It's limited by it. It's uninteresting compared to a realtime hack and slash game. It would still have strategy. And Pokemon it already open world. I just want it on a grander scale.
