:P They're bad enough at time travel plots in the spinoffs. We don't need it crossing into the main games.
I can't see them going any deeper than "go get badges and defeat the evil team" anyway - time travel seems well beyond the realm of a main series Pokemon game.
I feel obliged to break this awkward exchange with the trailer that came out the other day and it is pretty neato: Should be the right one. I think it's great except I am very disappointed the female protagonist is missing from it. ;_;
I've learned that size scales are pretty damn exaggerated in the Pokemon world, so nothing surprises me anymore. XD
