If this was a reboot, then that means that Ash never went through any other regions, he never caught any other Pokemon, and he doesn't know how to battle. All of those things are false, and anyone basing this off the first 10 episodes is a lunatic. I swear, some people have the memories of goldfishes, this exact same thing happened at the start of every other saga, this isn't late DP anymore, where old Pokemon exist. This is the beginning of a saga, where your lucky to even hear mention of old Pokemon. If this was a true reboot, we would never have any indication Ash could battle, we would see Ash not know how to do anything, and we would have awful battles and pity badges up the ying yang.
If BW is a reboot because "Ash's travel companions are Gym Leaders", then DP was a reboot since it was "Ash's regional girl was a Coordinator". BW will do things better and do things worse, just like AG did, and just like DP did. It'll take a little of each saga and improve on it, just like AG did, and just like DP did. Foresight people, use it, learn it, own it.
