I don't know about it being Your Mom but I wouldn't mind it being an older sibling or a regional professor. Or a Gym Leader again. A little more ethnic diversity would be nice to see. And I think Maple sounds like a good name for a female professor.

A region with a name that doesn't fit their naming pattern.
Something new, like... uh... Karnar?
I don't know...
Actually the Japanese name for Unova broke the pattern. And, the Unova elite four member Marshal is black. I want to see Prof. Oak again, from what I can see we won't be seing him this gen.
I like the 3d pokemon attack idea.
Damn nintendo for not letting us battle GEN IV with V
This conversation is getting to be very awkward.
That aside, it would be nice to have more than one game at the Game Corner.
Anywho, I know other people have mentioned this as well, but I want to see more of a family unit. It'd be really cool if they did a little change up and had a stay-at-home dad while mom was a researcher or even a gym leader. Heck, what if Dad is the Pokemon professor and Mom is a leading researcher? That'd be nifty. One of your rivals could be a sibling (maybe the boy or girl PC that isn't you) that starts his/her journey with you. Perhaps they are a year older than you and resent you because your parents held him/her back so you both could start your adventures at the same time, thus adding a hint of animosity between you and your rival. Hmm... just a thought.
OH! Something else I thought about: I want a jungle area. We've had tons of forests, but I would be really be up for a legit JUNGLE.
