SPECULATION TIME:
We've been talking about how they're likely to show a new 2-form pseudo-legendary such as Lucario and Zoroark
For all my purposes, I'll refer to this possible new pokwemon as "Nixye"

Lucario was based off of the aura, while zoroark was based off illusion

My guess for Nixye is a bit simpler, since this movie IS based off of genesect.

The movie is for now called "Extreme Speed Genesect"
So, given Genesect is the evil force in this film, they need something to counteract it

Now, one idea is a fire type pokemon (4x super effective), but I doubt that. A fox like fire pokemon (which is what the aforementioned pokemon have both looked like) will be too close to something from the Fennekin line

So what could combat something with Extreme Speed?

How about a pokemon based off of speed and being incredibly fast?
There's my prediction. Nixye's key trait, or one of them, will be incredible speed.

If true, hopefully it's nothing like sonic, because I just thought of that while writing this

But there's more

Now, this is speculation purely to connect this with an idea from earlier
However
Most people discredit this idea, and while I also do not find it LIKELY at all
On the one percent chance it DOES happen, there's this:

People mentioned a sound type way back
If there is a sound type, this pokemon could be it
Vibrating at supersonic speeds to move incredibly fast

However, remember this idea was founded not on being a "sound type" but to combat extremespeed genesect
So I do not wish to get into more arguments about a sound type, this is purely a connection
