...Why is it that people (might) think BW is a reboot. It's not a reboot because it features Ash, Team Rocket, Oak and Delia, and elements fromt he past sagas. Plus, it's still obvious and clear that Ash has been to all those past regions.
If this was a reboot, we wouldn't have any characters from Kanto-Sinnoh, and it would've started over witht he boy and girl from Black and White. But, it didn't, so Best Wishes is NOT a reboot.
I swear, people need to learn what the word 'reboot' actually means...
