Sorry, it's a long post.
Correct me if I'm wrong, but I think what's even more interesting than 3D graphics is a new battle structure and a deeper bonding with Pokemon.
I think we all saw 3D coming into play sooner or later, but it's more than just appearances that is keeping the franchise stale.
When same mechanics are used and reused, there isn't any room for "excitement" anymore; that is why I think the games have became a chore than enjoyment.
When we first played Pokemon as kids these "pixels and programs" seemed so magically alive, I still couldn't explain the element of "life" that I felt through the game.
I observe, personally, how with each game this sensation faded.
Perhaps I can simply attribute it to furthering of age.
However, what I felt through the trailer Tuesday morning, and the excitement that came to me when I imagined a new Pokemon world, seems to allow a small hope for that feeling again.
It sounds like a kid's innocence and imagination. Being a kid, everything new is magical and mindblowing. Then life and growing up strips it all away haha
