Is the next game even going to be a 3DS game? Because the 3DS is getting kinda old, and the New 3DS is out.

Honestly can we just get to gen 7 already, I want my shiny HD pokemon on NX ASAP.

It's obviously going to be on the 3DS. They had 2 Generations of games on the DS already. And until the NX comes out, the games will have to be on the 3DS.

What?
What does the NX have to do with this?

Gen 7

But by all accounts the NX doesn't seem to be a handheld...

And what does that have to do with the NX?
The Wii U got Rumble U. Why do you believe the NX will get any notable Pokemon game?

More Pokémon is always good, I had so much fun with X/Y & OR/AS, if they can finally give me the one thing I crave for it will be perfect.

People think it's a hybrid home console/handheld system (including me). So that's why.

So this little green guy is most likely related to Zygarde in a Phione/Manaphy type of way or a Carbink/Diancie kind of way.

Also, how much would it suck if they do do a Gen 6.5 but this little Green guy is the only new Pokemon added?

I would be mildly miffed. I don't want to buy a new game just for that little green blob.
