March Trailer for Extremespeed Genesect and the (Re)Awakening of Mewtwo (movie summary)

So, this video trailer for the 16th movie has surfaced and features some interesting information, and starts a bunch of speculation as well. The video can be viewed at:

Now, for the real news...
The trailer begins with a bunch of Genesect inside some tubes (Team Plasma?) with water or air, possibly generating more power for themselves. First, there are four tubes with purple Genesect (normal colored) and then, we get a close-up on the Red Genesect (leader?) and then, it zooms out showing them all. Then, the Genesects generate power and break the glass (fly out) as the Pikachu Logo appears. We see some Pokémon from Generation 5 and from other generations as four of the five Genesect (purple ones) come speedily into this town. Ash suddenly turns, and in surprise, sees the Genesect trying to attack the Pokémon and then, he tries to stop them, but then one Genesect, before he attacks, has to battle Pikachu because he tried to stop him as well. The scene cuts to some sort of mine area or whatever as Cilan and Iris gasp, and then some Genesect attack Team Rocket. The Red Genesect comes into the town as well, as Ash spots him. the Red Genesect hits Ash and Pikachu, and they fall over, as Ash says something. After he says one little thing, the Red Genesect gets ready to attack until...
Something comes out of the sky to the site. It's Mewtwo, who gives a huge blast towards the Genesect, creating an explosion at the battle site. Mewtwo is then surrounded by a blue aura, and the trailer ends with Ash saying "Mewtwo?" Ash's speech sounds as if he hasn't seen Mewtwo in a long time, which is true since he hasn't made a movie appearance since Mewtwo Retuens, so what could that mean...
Anyways, they cut to the movie logo, give a close-up on the Red Genseect and Mewtwo, and the screen fades to black. This appears to be a trailer that is unfinished, because it was so long ago and because I feel as if the words "To Be Continued" should've appeared, but that's just me. We already know what will happen to Mewtwo, but you guys (my fans) don't, and you will find out soon...
