I will be pissed off if it's a 7th Gen game. Because Gen 6 was one of the weakest made in my opinion.
I don't want to visit Kanto for a 5th time too, we got enough Kanto with Red/Blue/Green/Yellow, Gold/Silver/Crystal, FireRed/LeafGreen and HeartGold/SoulSilver.
A sequel or a third game will fix most of the stuff XY missed.
Thank you, really. This is exactly how I feel.
I mean, yeah, I'll buy the upcoming game no matter what, and I'll be happy that we're finally getting a new game. But...
Really, I'll just be so, so sad if they just drop Kalos the way it is. It's got so much potential, especially story-wise. It really wouldn't be hard after a two-year period to fine-tune the narrative and add in substantial gameplay content.
And I'm also getting rather...bored with Kanto, to put it kindly. It doesn't help that whenever Johto is involved Kanto is an obligatory addition, but whenever they throw in Kanto, Johto isn't included. To put it bluntly: I think Kanto is the weakest region, and just having a "new story" with new Gym Leaders won't fix that. Every time we get Kanto, it's always the same but with prettier graphics, and it gets stale after so many trips there.
I know it's the 20th anniversary and people want something all-new, but XY was supposed to be that "all-new, fresh experience," and I think it really deserves some proper fine-tuning. I think any sort of follow-up to Kalos (3rd version or sequels, if they feel it's truly appropriate, but as I've said before I'm still crossing my fingers for a 3rd version) would be appropriate for a 20th anniversary title, as long as it was really a full-fledged, enhanced experience.
